This overview is taken from “Single & Multiple User Specifications/Fall Arrest” found on
page 1 of the Instruction/Specification Manual 08

The CRA is rated for a single person with a maximum weight of 310 pounds including
tools and equipment and is rated for Fall Arrest.

The maximum length of one system is 120’ end-to-end.

The CRA is rated for up to 4 users when used in Fall Restraint or Work Positioning. A
maximum of 4 workers can tie-off to the horizontal line system on the CRA as long as
they are rigged in such as way as to not subject themselves to a free fall over the leading
edge.

The structure that the anchor is attached to must be capable of withstanding twice the
intended fall protection load, or 5,000 pounds as per OSHA 1926


Example: The Maximum Arresting Force for a shock absorbing lanyard or retractable lifeline
found in all personal fall arrest systems is generally 900 pounds or less. 900 pounds is the
“intended load” for the anchor, and twice that is 1,800 pounds. 1,800 pounds would be the
minimum strength requirement for the anchor attachment
The CRA with the supplied fasteners is rated at 5,400 pounds when attached to a wood deck or a
steel deck (see fig. 4 & 7 on page of the Instruction Manual). Minimum thicknesses apply

Specifications” found on page 1 of the Instruction/Specification Manual 08

Installation of the CRA is very straight forward. The anchor must be installed in the
center of a plywood sheet that is at least 4’x4’. The specification calls out for attaching to
¾” plywood. If the plywood is ½”, then another piece of ½” plywood backer board must
be installed either on the top or bottom of the primary piece of sheeting.

The Primary piece of decking must be secured through a minimum of 3 top-chords and
fastened on the perimeter edges 8” on-center with at least 21 ea. 2” x #14 deck screws.

Attach the anchor using the factory supplied (40 ea. 2 ½” x #14) hex head screws. The
fasteners must penetrate the backer board if one is to be used.

Always do a visual inspection from underneath the structure to make sure proper
penetration was achieved.

Please reference fig. #4, 5, and 6 on page 1 of the Instruction/Specification Manual

Use only factory supplied hardware unless otherwise noted in the
Instruction/Specification Manual

This overview is taken from “Steel Decking – 20 Gauge Minimum/Wood Sheathing/Rigid
Insulation” found on page 2 of the Instruction/Specification Manual 08

The CRA can be installed onto metal decking surfaces that are 20 gauge or thicker with
the factory supplied fasteners by simply centering the anchor base plate fastener holes
over the raised channel of the steel decking and attaching using the factory supplied 2 ½”
#14 fasteners. Here are some notes if the decking is 20 gauge or less:



Attach a second layer of metal decking that is 3’x3’ with #14 deck screws 8” on center through all
raised channels of the metal decking. A 3’x3’ piece of pressure treated plywood backer board
attached to the underside of the steel decking that is secured with grade 8 bolts can also be used.
A 3’x3’ piece of plywood decking placed on top of the metal decking and position the anchor over
the wood sheeting so that the hex head screws penetrate the raised channel of the metal deck.
Secure with 36 of our factory supplied hex head fasteners
If rigid insulation is being used, then the anchor needs to be bolted to the structure using the
following method: bolt the anchor base to a ¾” x 24” square pressure treated plywood backer
board on the underside of the primary sheathing. Drill through the insulation board, primary
sheathing and backer board. Use 8 ea. ½” grade 8 bolts of sufficient length and secure with lock
nuts and washers. Position the bolt holes over the raised channels if possible.

This overview is taken from “Concrete Slab/Rigid Insulation” found on page 2 of the
Instruction/Specification Manual 08

The CRA has provisions so that it can be attached to a concrete slab. The concrete must
be a minimum of 4” thick and rated at 2,000 p.s.i. There are 8 ea. 9/16” holes in the base
of the CRA – these are the mounting holes for the concrete impediment bolts. Use a ½”
impediment bolt that extends down at least 3”. Note that the bolts must maintain a
margin of ½” from the bottom of the concrete slab. The concrete must be cured
sufficiently to withstand the intended fall protection load before using for fall protection.

Review for concrete decks:




All 8 mounting holes must be utilized
Use only ½” impediment bolts (wedge anchors)
that have a rating of 6,000 pounds or higher
The concrete must be a minimum of 4” thick
It must have a minimum p.s.i. rating of 2,000

Beams” found on page 2 of the CRA
Instruction/Specification Manual 08

The CRA may be attached onto a steel or wood beam
using a backer plate that mirrors the mounting
plate. The anchor attached to the beam by using
“all-thread” or grade-8 bolts. The backing plate is
3/8” thick steel and has 9/16” holes. The all-thread
or grade 8 bolts need to be ½” x -----

Horizontal Line System (HLS)
The Commercial Roof Anchor has the ability to be used as a mounting system for a
horizontal lifeline. There are 2 ways that this can be done:
#1 – End Style anchors can be placed every 20’ and a cable can be run through the top of
the anchor point. The user must disconnect his system and reattach to the next run of
20’ of cable.
#2 – Pass Through style anchors allow the user to “pass-through” the anchor and thus
stay connected to the system 100% of the time. A special top is manufactured onto the
CRA and allows a “O” ring to pass through the cable guide.

Horizontal Line System (HLS) “Description of PTT Anchor”

Description of the PTT Anchor:

The Pass Through Top Anchors are fitted with a special ½” cable guide at the top of the
anchor. The cable is strung through the PTT and allows an special “O” Ring to pass
through the cable guide with a lifeline or lanyard attached. The feature allows one or more
workers to travel the length of the horizontal line without having to disconnect their PPE,
lifeline, lanyard, or shock/energy absorber.

Horizontal Line System (HLS) “Specification of Use”:

When building a Horizontal Lifeline System using the CRA’s and CRA-PTT’s, part #1032
or #1033 must be used as the primary end point anchors. Use the PTT anchors as the
intermediate anchor points that go in between the end anchors. The maximum length
of each horizontal line is not to exceed 120’ and spaced no more that 20ft apart.
Do not use the PTT anchors for horizontal line ends or corners. PTT anchors may be
used for one person to connect his PPE provided the connectors are compatible and
prevent disengagement.

NOTE: Custom CRA & CRA-PTT risers can be fabricated for pitched roofs.

Horizontal Line System (HLS) “Cable Attachment”:

Prior to rigging the cable ends, install up to 4 “O” rings onto the cable. There are 2 ways
to do this – with or without turnbuckles:

End Loops without Turnbuckles:


End Loops with Turnbuckles:


Add 36” to the length between end/corner anchor points (see fig. 22a and 22c) Feed 18” of cable
through the riser top connecting ring and attach cable clamps as shown in (fig. 20). Tighten clamp
nuts to 45 lbs. Repeat for the opposite end.
Use the same formula as above and deduct 29” of cable length for each turnbuckle that is used.
Adjust the turnbuckle threads out to allow a minimum of 2” of thread buffer to remain. Connect
one end of the turnbuckle to the end/corner anchor point (see fig. 22a) and secure the shackle pin
and cotter pin. Repeat the procedure for the opposite end. For systems longer that 60’ total we
recommend using 2 turnbuckles.
Cable Slack:

Always maintain a minimum of 2” of slack between end/corner anchors. A failure to do so may
result in damage to the anchor fasteners or the supporting structure.

Horizontal Line System (HLS) “Energy Absorbers”:
 Personal Protective Equipment energy absorbers are required for each person connected
to the HLS and must be attached to the “O” ring as shown in fig. 16c. Do not use webbing
type energy absorbers to attach a cable to an anchor.
 A metallic energy absorber (#1059) may be used as a component of the horizontal lifeline
system as shown in fig. 17 and 23. Attach the absorber to one or both CRA end/corner
anchors. Do not attach absorbers to a PTT anchor. Turnbuckles may be connected
before or after the absorber.
 Do not use HLS if any of the following conditions are observed:
