B-Line Eaton series data and low support fasteners, Cable hook, Wall mount, 3/4" Hook, 1 J-hook, Orange, Load capacity of 30 lbs, Steel

Wall mount is what this one is built for. The BCH12OR is a wall mount cable hook, so it fastens flat to a vertical surface such as a stud face, plywood backboard, or block wall, and the cable runs horizontally through the saddle. If you need to hang off threaded rod, beam flange, or ceiling wire, that calls for a hook with the matching attachment accessory instead.

Yes, it is UL/CUL listed, which is usually what a spec on a commercial or institutional data install is asking for on cable support hardware. It is a steel hook, so it also stands up better to handling during rough-in than a plastic support.

Compact. It measures 3.18 in height, .88 in width, and 1 in length/depth, and weighs .07 lb. That small footprint is what lets you space them down a stud line or inside a tight ceiling cavity without the hook body fouling other services. The light weight also means the fastener you choose, not the hook, governs the pull-out strength of the mount.

A J-hook such as the BCH12OR is for supporting cable along an accessible pathway, ceiling space, or backboard where the cable is open and free to be added to later. It is the fast, low cost option when moves and adds are expected. Conduit or cable tray is what you use where the cable needs physical protection, where it is exposed in a finished or rough industrial area, or where a drawing calls for a closed raceway. Hooks do not replace conduit where code or the spec demands a raceway.
