Drain Fittings ST
Installation Instructions (valid for all drain fitting types)
1. Create a hole on the duct wall according to the required drain fitting size using a cone-cutter (see „dimensions“).
2. Insert the drain fitting from inside the duct and, on the outside, the funnel or washer and the nut. Tighten the nut until
the duct wall is deformed enough to create a funnel-like area. Applying some grease between the nut and the fitting
will ease this operation. Caution: do not over-tight the nut on the ST-K drain fittings, as the brass conical washer is
less sturdy than the funnels of the other drain fitting
types which are made of galvanized steel.
In case the drain fitting rotates when tightening the nut:
a special flat area has been created on one side of the
fitting. It provides a firm hold using pliers in order to
prevent the fitting from rotating when the nut is tightened
while preventing any damage to the threads.
3. The cap is only used if no drainage has been planned
(please order separately).
4. On the ST-R drain fittings two markings have been
created on the saddle funnel, allowing to align it with
the axial direction of the round duct.
Maximum duct wall
thickness: 1,5 mm
Holding-Wrench – Eases the Installation of the Drain Fittings:
The Holding-Wrench allows tightening the drain fittings
easily without damaging the threads. It is also recommended
to use this tool when a PTFE seal ring (to be ordered
separately) is required to increase the drain fitting‘s
liquid tightness.
The assembly is carried through as indicated above,
excepting that the Holding-Wrench is used instead of the
pliers. Please make sure that the lever faces the fitting‘s
flat surface. Then tighten the nut using a standard or
a pipe-wrench.

build the blade and fasten it.
• The duct walls are clamped
and stiffened between two
pressed plates.
• Easy installation.
• Continuous variable position
adjustment of the blade.
• Comfortable operation.
Openings
which allow
to turn the
damper
blade
The duct wall is clamped
between two pressed
plates. When the red knob
is tightened the damper plate
is locked without any slack.
On large
dampers this
washer can be
replaced by an
operating lever
This knob is
loosened for
damper
adjustment
and tightened
to lock it into
position.
92
The damper blade has to be
manufactured according
to size and rigidity
requirements.
Pivot pins are
compressed on springs
when you install the
damper into the duct.
When they are aligned
with the pivot holes in the
duct they spring out and
position the damper.
On this side the plates
are clamped together by a
spring tension and can be
rotated freely

Blade Manufacture Instructions
d1
Depending on the stability
requirements, either single or
double blade dampers are
suitable.
In both cases the sides have
to be folded right-angled 20 to
25 mm for stiffening and fixing
purposes.
KS 10: d1 = 95 mm
KS 25: d1 = 2
30 mm
Installation Instructions
1
Fixing the damper blade:
Spot-weld the damper blade on the
inner pressed plates. The center line
marked on the inner pressed plate
shows the position of the damper
blade. Damper blades should be
manufactured within a tolerance of
2 mm to prevent duct wall bulging
or being pulled inwards on assembly.
The dimension should be verified
before fixing the second plate.
2
Cone cutters are very helpful
for drilling the pivot holes:
KS 10 = 14 mm Ø, KS 25 = 20 mm Ø
3
To install the blade in the duct, compress the spring loaded pivot pins
and slide the assembly into
the duct until the pivots spring
out through the pivot holes.
4
Fix the outer plate with the locking
knob so that the triangular arrow
shows the position of the
damper blade. Then
fix the plate on
the other side
METU-SYSTEM Catalog 6b (August 2013)
93
Control Dampers KS
Operation
To adjust the damper, release the
knob until the plates are no longer
clamped. Adjust to the required
position using the lever or actuator
plate with reference to the arrow which
is indicating the blade position. Then
tighten the knob to lock the damper
into position.
LIGHT DUTY DAMPERS
A lever is not required to operate
them. Rotate the actuator plate with
your fingers, as depicted (only KS 25).
The fixing screw on the opposite side
remains tightened during the adjustment of the damper, since the plates
are pressed together by the force of
the springs.
MEDIUM DUTY DAMPERS
For these kind of dampers the lever
should be positioned centrally on the
plate, as illustrated.
Dampers are also suitable for motor
actuation.
In that case the knob must not be
tightened too much since the blade
should be able to rotate easily.
HEAVY DUTY DAMPERS
The lever should be positioned on one
side to obtain maximum leverage.

Tie Bar Fittings
• Assembly elements for the fabrication and installation
of tie bars.
• The duct wall is clamped
between two rigid discs over a large area for an optimal load distribution
• The tie bar is made of
conventional ⅜” galvanized
tubing (DIN 2440).
Special expanding
plug for 3/8” tubing.
Hexagon socket

M6 x 40
Rigid pressed galvanized pressure discs.
Crossing tie bars are joined using a
clamp which can be fitted at any
angle by tightening the M8 screw.
The clamp is specially
formed for the tube-Ø
to prevent slippage.
Installation Instructions
1. Determine the position of the tie bars. If duct work is stiffened, position the tie bar at the intersection of the stiffening.
2. The overall length of the tie bar is equal to the clear internal duct dimensions. If the cross stiffening is external
(as it can be found on positive pressure duct work), add 20 mm to the tube length. If the cross stiffening is internal
(as it can be found on negative pressure duct work), deduct 20 mm from the tube length.
3. The tube length is the tie bar overall length minus 2 mm. Hammer in the expanding plugs flush with both
ends of the tube.
4. Drill 7 mm Ø holes in the required locations.
5. Fit the tie bar with one disc on the inside and one on the outside on each end of the tube.
Tighten the screws with a 5 mm Allen key to expand the plugs.
6. Crossing tie bars can be connected with a cross tie. Make sure that the tubes are straight
before securing the cross tie.

Isolation Hangers SI
• For the sound isolated suspension of ductwork and equipment
with M8, M10 and M12 threaded
rods.
• A large piece of rubber is placed
between two sturdy tension
brackets.
• Even if the rubber is damaged
(for example through a fire), the
suspension will not break down.
• The load strain can be read on a
scale. It allows to use the loadbearing capacity of the hanger
to its full extent while making
sure that the load is evenly
distributed among all hanging
points.
The sturdy tension brackets have a
much greater load-bearing capacity
than the corresponding threaded rods
The load can be
read on a scale
The rubber padding which prevents
vibrations from being transmitted is,
depending on the Isolation Hanger type,
between 45 and 55 mm thick
The open space corresponds
to the width of the nut, locking the

Hanger Profiles MS
• For the support and fastening
of ductwork and other
equipment.
• The special profile shape
provides a high bending
resistance.
• A range of accessories and
ingenious details offer an answer to practically any
suspension requirements
with only one system.
The high profile section provides a
high bending resistance compared
to the necessary material, and
consequently an optimal
price/loading capacity ratio.
The oval holes allow the passing of
threaded rods or bolts, thus increasing
the installation possibilities
The MS Isolation Pads provide optimal
sound proofing.
The slot in the Hanger Profile allows to
insert the Isolation Pads at any desired
position.
The material around the oval holes is
turned inside and provides extra rigidity
in the hole area (also available without
the holes).
Applications
The MS Hanger Profiles have been initially designed to answer ductwork installation requirements. The variety of these
requirements being relatively broad, the MS Hanger Profiles can also be used for other application fields such as
heating and sanitary installations.
The loading capacity being a critical factor, three different profile sizes have been created, being able to support loads
from a few kilos (small ductwork) to more important weights such as 4 meters wide ductwork, silencers, filters,
accessories or other equipment. The loading capacity can also be multiplied by coupling several MS Hanger Profiles.
Finally, a few accessories give a greater flexibility to numerous suspension requirements. In an attempt to keep the
number of parts to a minimum, each one of these accessories has been carefully designed to cover several combination possibilities.

When using the field trial method, the Hanger Profile type
is selected by the installer. Then, if the deflection is found
to be too important (that is more than 0,4 % of the length)
it can be reduced by using a larger Hanger Profile type,
coupling several profiles together or by installing a third
threaded rod.

Hanger Profiles MS
End Brackets and Clamps
The MS End Bracket is inserted as a connecting part
between the Hanger Profile and the threaded rod.
Advantages: - High loading capacity
- Aesthetically pleasing
- Independence from the profile holes.
When only one duct is going to be suspended, the
Hanger Profile section is cut 20 to 40 mm longer than
the duct width. For all other applications, cut the
Hanger Profile sections according to your needs.
If isolation is required, first insert the Isolation Pads on
both ends of the Hanger Profile.
The End Brackets are slightly tapered so that they wedge
into the profile and must be hammered home hard up to
the stop. To prevent the End Bracket from being damaged,
the protective cap which is included in each sack of End
Brackets, should be used.
The End Bracket can be fitted into short profiles in a
vertical position. Long Profiles should be put in a
horizontal position against for instance a wall, in
order to hammer in the End Brackets.
Max. threaded rod Ø for: End Bracket MS 3 = M8
End Bracket MS 5 = M10
End Bracket MS 8 = M12
If the maximum threaded rod diameters are used, no
washers are needed. If smaller threaded rod diameters
are used, corresponding washers must be installed.
If in some special cases the End Bracket is not sufficiently
secured, it is possible to secure it in place with screws or
rivets.
As an alternative to the End Bracket, the threaded rod can
be passed through the oval holes of the Hanger Profile
and fixed by a MS Clamp.

Hanger Profiles MS
Isolation Pads
The use of MS Isolation Pads provides a cost effective solution if sound isolation is required.
Because the duct weight is mainly concentrated on the duct corners, the Isolation Pads installed at the corners have to
support the most important loads. Because of its high loading capacity a rubber with 60° shore hardness has been chosen. The effectiveness of the Isolation Pad decreases rapidly when it is overloaded.
1
At the end sections of the Hanger Profile the Isolation
Pad can be easily inserted.
2
If the Isolation Pad has to be installed further along the
Hanger Profile, it can be hammered on.
1
2
Normally only two Isolation Pads are required (one at
each edge of the duct work).
On wide duct work, however, additional Isolation Pads
must be installed to prevent the bottom of the duct from
touching the Hanger Profile.
Length of the Isolation Pads: MS 3 = 60 mm
MS 5 = 80 mm
MS 8 = 100 mm
500-800
mm
The bottom corners of the duct work greatly compress the
Isolation Pads. Softer Isolators (foam rubber for example)
may be compressed to such an extent that they become
ineffective.
This graph shows to which extent the Isolation Pad is
compressed depending on different loading capacities.
Maximum loading capacity:
MS 3 = 2000 N
MS 5 = 3000 N
MS 8 = 3500 N

Support Brackets AL
• For the suspension of
rectangular ductwork with
threaded rods.
• Sturdy construction with
loadbearing capacity up
to 1500 N
• Large supporting surface area
prevents the edge of the duct
from being deformed.
• Easy installation.
Duct wall
The shape of the Support Bracket is
designed to distribute the load on the
threaded rod and to hold it tight against
the duct wall in order to ensure that the
nut provides the main support.
The large surface area prevents
the edge of the duct from being
deformed
Two rivets or drill screws are used
to secure the AL Support Bracket
into place
The nut is partly under the edge of the
duct and therefore supports the main
load while reducing the strain on the
threaded rod.
Load-bearing Capacity and Dimensions
The two AL Support Brackets have the same sizes and differ only in the diameter of the hole for the threaded rod:
length 37 mm, width 50 mm, height 37 mm. The load-bearing capacity always depends on the strength of the duct
work, since the duct wall will buckle before the bracket deforms. With a duct wall thickness of 1 mm for instance the AL
Support Bracket loading capacity is 1500 N*.
* The indicated maximum load-bearing capacity is in accordance with the European Norm EN 12236
and can therefore be used integrally. The breaking load is three times higher.
Installation Instructions
Press the AL Support Bracket tight against the duct wall and drill through the 5 mm guide holes to suit rivets or self-tapping
screws. The threaded rod can be positioned either before or after the fixing of the Support Bracket on the duct wall.
Sound isolation:
If sound isolation is required, we recommend the use of SI Isolation Hangers for loads up to 1500 N, or the use of
DB Ceiling Brackets.

Installation Instructions
Instead of the standard bolts and nuts two AB Hanger Bolts are fitted in the holes of the duct´s bottom corner pieces.
Care must be taken when tightening the bolts that the hole for the support threaded rod remains vertical.
Only the bottom holes must be used, not only because it allows adjustment of the support rod, but also for safety
reasons - the bottom corners can never be pulled out from the duct.
Sound isolation: With SI Isolation Hangers or DB Ceiling Brackets.
If ducts have external insulation, the supporting rods can be approximately 5 cm longer and a Long Nut (please refer to
section “GS Threaded Rods/LM Long Nuts“) or collar 30 mm long is installed instead of the normal nut. This enables the
height of the duct to be adjusted even after it has been insulated.
