Simple Pitchfork Stacker
Single connection for box and branch: crossbar carries the box on a spring steel clip, stacker hooks carry the MC up the rod.
Give us the size, drop and service and we’ll spec the part number and quote the build.
Box and MC branch on one support.
Rated capacity
90 lbs
Support rated load, listed per ICC-ES PMG-1840 Table 1

03 · Notes
From the Technical Data Sheet
- Single connection for box and branch: crossbar carries the box on a spring steel clip, stacker hooks carry the MC up the rod.
- 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.
