03 · Notes
From the Technical Data Sheet
- Single connection for box and branch: the crossbar carries the box on a spring steel clip.
- Enables airflow to eliminate bundling limitations. NEC 310.15(C)(1)(d).
- Crossbar height 10 in. typical; fixed dimensions can be changed per order.
- Rigid connection to structure eliminates the need to tie off to the ceiling grid below. NEC 300.11(A).
- Finish: zinc plated.
- Support spacing governed by the applicable local building code.
- Dry locations only, per the listing.
- Rated load carries a minimum 4:1 factor of safety on ultimate tested capacity per ICC-ES LC1041 and UL 2239.
- The rated load applies to the support assembly only; the attachment to structure is evaluated separately (Section 01).
- Seismic: per ASCE 7, power actuated fasteners are limited to 90 lbs of tension in Seismic Design Categories C (Ip = 1.5), D, E and F. The capacity published here is already at or below that limit, so it is unchanged on a seismic project.
- Drawings not to scale.
