Metallics MBR100WS Bridle Ring 1" Ws St-zn (Bag 10)

The MBR100WS is a 1 inch bridle ring, so the loop gives you a 1 inch opening to run low voltage cable, data, or fixture wire through. Size the ring to the finished bundle, not the single cable, and leave room so you are not compressing the jackets.

It is the wood screw version (WS), so the integral threaded point drives straight into wood, joists, studs, or blocking with no separate anchor or fastener to buy. Into steel stud, concrete, or threaded rod you would want a different mounting style of bridle ring instead, since the wood screw tip will not hold in those substrates.

It is zinc plated steel, which handles dry interior and normally dry unfinished spaces like attics, basements, and joist bays. Zinc plating is a corrosion coating, not stainless, so for wet, exterior, or corrosive locations choose a ring rated for that environment.

Order Metallics MBR100WS. That single part number covers the 1 inch wood screw zinc plated steel ring in the 10 piece bag, so there is no separate size or finish option to specify.

A bridle ring like the MBR100WS is a cable support loop, not a cable clamp or staple. It is normally used to carry and route communications, data, and control cable through framing. It does not secure a cable the way a listed staple or strap does, so where your installation calls for the wiring method to be secured and fastened, use the proper strap for that cable type and keep the ring for support and routing.

They ship as a bag of 10. For rough-in planning, figure one ring every few feet of run plus one at each direction change, so a single bag covers a short branch and a larger pull takes several bags.
