Metallics MBR400WH Bridle Ring 4 MS &Saddle St-Zn (10 pcs)

It mounts on a machine screw stem with a saddle, so it threads into a machine screw thread rather than driving into wood like a lag or wood screw version. On a steel beam, strut, or threaded insert you have the mating thread already; in concrete or wood you need to add the appropriate anchor or insert to accept the machine screw. The anchor is not part of the pack, which contains 10 rings.

A bridle ring is a loop-and-stem support used to carry low voltage, communications, or control cable along structure so the bundle is held off the deck and out of other trades' way. The MBR400WH is a 4 inch ring on a machine screw stem with a saddle, made of zinc plated steel, and it ships 10 pieces to a pack.

The MBR400WH is the 4 inch size, the largest of the common bridle ring sizes, so it takes a substantial bundle of Cat6, coax, or fire alarm cable. Standard practice is to leave the bundle loose in the ring rather than packing it full, so size up the ring to the finished bundle plus room for adds, not to the day-one count.

No. Bridle rings are cable supports for low voltage and communications runs. They are not a raceway and they are not a substitute for conduit, clamps, or straps on power circuits, so keep branch circuit wiring in its own approved support method and use the 4 inch rings for the data, coax, and control bundles.

The MBR400WH is zinc plated steel, which is a dry interior finish. It works in conditioned and typical plenum or ceiling space, but in wash down areas, exterior runs, or damp garages the plating will eventually rust at cut edges and threads, so specify a stainless or hot dip galvanized support there instead.
