ICC Issues Evaluation Report on CMC Seismic Perimeter Clip |
ICC Evaluation Services (ICC-ES) has recently issued an evaluation report (ESR-2282) on the 1496 Seismic Perimeter Clip from Chicago Metallic Corporation. The seismic perimeter clip, which is used in suspended ceilings to stabilize main and cross tees at the perimeter has been evaluated and found to meet the applicable section of the IBC 2006 for use in seismic design categories A, B, C, D, E and F. The clip can be used in lieu of stabilizer bars that are designed to prevent the tees from spreading apart during seismic activity, and allows for the use of 15/16” wall angle instead of the standard 2” angle in design categories D, E and F.
Secure, Faster Installation
Brian Valdez, product manager, explains, "Perimeter clips attach to a wall molding and the main or cross tees that support ceiling tiles. Architects and builders prefer Chicago Metallic's seismic perimeter clip because it produces a sleeker looking ceiling. Here is why: In Category D, E, and F seismic installations, the International Building Code (IBC) requires stabilizer bars and a 2-inch wide perimeter wall molding to prevent the ceiling grid from spreading along the molding. The seismic perimeter clip allows installers to use a 15/16-inch molding and no stabilizer bars. It's a cleaner look that most designers prefer."
Installers prefer the seismic perimeter clip because it speeds installation. They do not have to risk using unapproved construction techniques to meet seismic codes. And, where local building code permits, the clip eliminates the need for any additional hanger wires.
The ICC evaluation report also brings a new comfort level to local building inspectors because the 1496 Seismic Perimeter Clip, as an alternative, has been evaluated against the applicable sections of IBC 2006. Finally, the brass-color, commercial quality steel clip is easy to see so inspectors can quickly confirm that the clip has been installed at the required intervals.
