B-Line Eaton series cable support fasteners, Conduit and cable, Flange, 0.062lbs, Flexible conduit/cable fasteners, .13" Min, .25" Max mount size, .44

No fasteners and no drilling. It is a flange-mount clip: it snaps onto the edge of a steel flange, such as a bar joist, beam, or strut edge, and the cable clips into the saddle. That is why the mount range is given as a thickness, not a hole size.

Flange thickness from 0.13 in to 0.25 in. That covers most light structural steel edges and joist angles. On anything thinner the clip will not grip; on plate heavier than 1/4 in it will not seat, and you want a beam clamp instead.

Zinc plated steel. That suits dry and normally damp indoor environments like mechanical rooms, ceilings, and parking structures under cover. For wet, coastal, or corrosive exposure, specify a stainless or hot dip galvanized support instead, since zinc plating is a light protective coating.

Spacing is set by the wiring method and the code, not by the clip. For NM cable, supports are generally required within 12 in of a box and at intervals not exceeding 4-1/2 ft, so one clip at each flange crossing in that range. Each clip is a single cable carrier, weighing .012 lb, so quantity is driven by run length and the number of cables, one clip per cable per support point.

It is a compact clip, 1 in by 1 in by 1 in. That matters when you are stacking runs close to deck or working above a hung ceiling grid, since the clip adds roughly an inch of profile off the flange edge.

CE marked. That is the only certification carried on the BXM-1214 record, so if your specification calls for a specific UL listing on cable supports, confirm the requirement against a listed product.
