B-Line Eaton series data and low support fasteners, Zinc plated finish, 50 lbs, Steel, 1.25", 10-24" x 9/16", Used with fasteners for addiitonal supp

The BR-20-4T bridle ring is rated for a 50 lb load, and the ring opening is 1.25 inches. That 1-1/4 inch loop is what actually limits the bundle: it sets how many low voltage or datacomm cables you can pass through before you need a larger ring or a second run. The 50 lb figure is the support rating, not an invitation to overfill the loop.

Yes. The threaded bridle ring is cULus Listed, which covers it for both US and Canadian installations. Contractors supporting datacomm and low voltage runs above ceilings typically need that listing on the record for inspection, and it is on this part.

Yes, in most cases. The threaded bridle ring has a 10-24 x 9/16 inch machine thread and is intended to be used with fasteners for additional support, so you supply the anchor that receives it: a threaded insert, a beam clamp with a 10-24 tap, a rod coupling, or a driven fastener with a 10-24 female thread. Count those into the takeoff at one per ring.

A 1.25 inch loop handles a modest bundle. Keep in mind the ring is a support, not a raceway: cables have to stay loose in the loop so you are not compressing the jackets or exceeding bend radius at the support point. If your bundle is growing past what fits freely in 1-1/4 inches, step up to a larger ring size rather than cramming it.

Outside diameter is 2 inches and overall height is 1.75 inches, with the usable ring opening at 1.25 inches. The difference between the 2 inch outside and the 1.25 inch opening is the steel of the ring itself, so plan clearance off the 2 inch figure when you are working tight to a joist or a duct.

The listed product weight is 15.2 lb, which is a carton quantity, not a single ring. A steel ring this size weighs ounces. Order it expecting a bulk pack for a full pull, not one piece for a single drop.

The BR-20-4T is steel with a zinc plated finish, which is a dry indoor interior finish. It suits ceiling plenums, IDF rooms, and interior joist bays. For a wet, corrosive, or exterior run, specify a stainless or hot dip galvanized support instead, since zinc plating will eventually rust in standing moisture.
