B-Line Eaton series hanging system, KwikWire wire rope, Toggle termination, 1/16" wire max, 180" wire length

Toggle termination is the anchoring end of the KwikWire assembly, meant for hollow structure, a toggle passes through a drilled hole and flips open behind the deck or panel to bear against the back face. That is the end that goes up to the structure, the gripper end takes the fixture load. If your overhead is solid concrete or structural steel, a toggle is the wrong end and you want an eye, hook, or beam clamp termination instead.

Yes, it carries a cULus Listing, so it is recognized for both US and Canadian installations. That matters on inspected work where the AHJ wants a listed suspension method for luminaires, cable tray, or other electrical support rather than field-rigged wire.

Yes, that is how these hangers are meant to be used. The gripper sets at whatever drop height you need and the tail is trimmed off, so the 180 inch rope is a maximum working length, not a fixed one. Order the length at or above your longest drop and cut down, one part number covers a range of heights across a job.

The 1/16 inch class of KwikWire, which is what the .062 inch max diameter on this kit refers to, is the lightest rope in the family and is the one normally run for luminaires, small cable tray, and signage. Heavier suspended loads move up to a larger rope diameter kit. Size the hanger to the fixture weight and the number of drop points you are using, and split the load across multiple hangers rather than pushing one 1/16 inch rope.

It is sold as one assembly, wire rope plus toggle termination, under the single model BKT-063-180K. There is only one configuration of this part, so there is nothing to specify beyond the length and the termination style. What you may still need on the job is the fastener or hole prep at the structure and whatever attachment ties the rope to your fixture.
