Structural
2.0 USES
The Seismic Fixture Clamp (SFC) is used to provide positive
attachment of recessed fluorescent light fixtures (luminaires)
to framing members of metal suspension systems for
acoustical tile and lay-in ceilings, complying with Section
803.9.1.1 of the IBC and footnote 1 to Table 25A of the UBC,
to resist gravity and seismic loads. In addition, the SFC is
used to provide an alternative to the two slack No. 12 gage
wires required by Ceiling and Interior Systems Construction
Association (CISCA) documents CISCA 0-2 and CISCA 3-4
and Section 25.213 of UBC Standard 25-2.
3.0 DESCRIPTION
3.1
Seismic Fixture Clamp (SFC):
The SFC is fabricated from No. 20 gage [minimum basemetal thickness of 0.0358 inch (0.91 mm)] galvanized steel
complying with ASTM A 653 SS Grade 33, with minimum
yield and ultimate tensile strengths of 33 and 45 ksi (228 and
310 MPa), respectively. The clamp is cold-formed in several
configurations for specific orientation of the luminaire to the
main and cross runners of the suspension system, and is
prepunched for the fasteners described in Section 3.2 of this
report. See Figure 1 for a typical SFC.
3.2
Fasteners:
The fasteners used to attach the clamp to the main and cross
runners of the suspended ceiling grid are Compass
International No. 10 by 3/4-inch-long (19.1 mm), DARTS
Brand, self-drilling, self-tapping steel screws recognized in
ICC-ES evaluation report ER-5202.
3.3
Luminaires:
The luminaires must comply with the requirements of the
applicable code and must be constructed from a minimum of
0.024 inch-thick (0.61 mm) steel complying with ASTM A 366,
having minimum yield and ultimate tensile strengths of 26 and
45 ksi (179 and 310 MPa), respectively. The maximum weight
of the luminaires is limited to 56 pounds (25.4 kg).
3.4
Metal Grid Components:
The main runners and cross runners are formed, respectively,
from steel having minimum uncoated base-metal thicknesses
of 0.013 and 0.010 inches (0.33 and 0.25 mm) and complying
with ASTM A 653 SS Grade 33. The runners must have a
vertical “T” component at least 1 inch (25.4 mm) long, and not
to exceed a maximum length of 111/16 inches (42.9 mm) and
a maximum thickness of 5/16 inch (7.9 mm).
4.0 INSTALLATION
One SFC must be installed over the main and cross runner
intersection at each of the four corners of the luminaires in
accordance with Figure 2 of this report. Two fasteners must
be used to attach each clamp, with one fastener installed
through the web of the cross runner and one fastener
attached through the web of the main runner. The tab at the
end of the flange on the SFC must be installed between the
cross runner and the clamp. In jurisdictions adopting the IBC,
to comply with Section 1613.1 and 2506.2.1, installation of
the lighting fixture must comply with CISCA 0-2 or CISCA 3-4
as referenced in Section 13.5.6.2 of ASCE 7, which is
referenced in Section 1613.1 and 2506.2.1 of the IBC, except
that the two No. 12 gage slack wires attached to the luminaire
are not required. In jurisdictions adopting the UBC, the
installation of the luminaire must comply with Section 25.213
of UBC Standard 25-2, except that the two No. 12 gage slack
wires attached to the luminaire are not required.

Section 803.9.1.1 and as required by Section 1613.1
and 2506.2.1, which references Section 13.5.6.2 of
ASCE 7. For jurisdictions adopting the UBC, the grid
system shall be installed in accordance with UBC
Standard 25-2.
5.0 CONDITIONS OF USE
The Seismic Fixture Clamp (SFC) described in this report
complies with, or is a suitable alternative to what is specified
in, those codes listed in Section 1.0 of this report, subject to
the following conditions:
5.1
5.2
5.3
Installation of the SFC shall comply with this report, the
manufacturer’s published installation instructions and
the applicable code. The manufacturer’s published
installation instructions shall be available at the jobsite
at all times during installation. When conflicts arise
between this report and the manufacturer’s published
installation instructions, this report shall govern.
Use of the SFC is limited to attaching recessed
fluorescent light fixtures (luminaires) to framing
members of metal suspension systems for acoustical
tile and lay-in ceilings described in Sections 3.3 and 3.4
of this report.
In jurisdictions adopting the IBC, the SFC must be
attached to a grid system meeting the requirements of
5.4
The use of the SFC in a fire-resistance-rated ceiling
assembly is outside the scope of this report.
