Metallics MBR150WH Bridle Ring 1-1/2 MS &Saddle S (10 pcs)

The MBR150WH is a 1-1/2 inch bridle ring, so the ring opening is sized for cable bundles up to roughly 1-1/2 inches in diameter. Low voltage installers use that size for a modest bundle of Cat6 or coax runs; step up to a larger ring if the bundle will grow beyond the ring's inside diameter, since overfilling a bridle ring is what causes cable damage and fill violations.

It ships as a machine screw style ring with a saddle base, so it mounts flat against a surface (wood joist, plywood backboard, or a strut/box with the correct threaded hole) using the saddle rather than threading directly into material like a lag or wood-screw version. You supply the fastener and, on masonry or drywall, the appropriate anchor. If you want a ring that drives straight into a wood joist with no saddle, order the wood-screw version instead.

A bridle ring like the 1-1/2 inch MBR150WH is the compact, inexpensive choice for small bundles and short spans where you only need to keep cable off the ceiling grid and out of the way. A J-hook carries a wider bundle with a flatter bearing surface and is the better pick when you are running a large trunk of data cable or need to respect a tighter bend radius on a heavy bundle. For a few drops along a wall or joist, the bridle ring is the usual answer.

Bridle rings are cable support hardware for communications and low voltage runs, not a substitute for the straps, staples, or conduit required for power wiring. Use the MBR150WH for data, coax, fire alarm, and similar signal cable; for NM cable or conduit, use the listed strap or clamp for that wiring method.
