B-LINE B4089ZN – Frequently Asked Questions
1) What size cable does the B-Line B4089ZN Insuclamp handle?
The B4089ZN is a 4 inch Insuclamp cable clamp, so it is sized to wrap cable in that diameter class. Overall the clamp measures 4.62 inches in height. If your cable OD falls well under 4 inches, step down to a smaller Insuclamp rather than shimming this one.
2) Is the B-Line B4089ZN cable clamp steel or aluminum?
Steel, with an electro-plated finish. That combination suits dry indoor electrical rooms and protected interior runs. For sustained outdoor exposure, wash-down areas, or corrosive environments, specify a hot-dip galvanized or stainless clamp instead of the electro-plated version.
3) What is the exact part number to order the B-Line 4 inch Insuclamp?
Order it as B-Line B4089ZN. That is both the model designation and the manufacturer part number, so there is no separate suffix to specify for finish or size, it is a single configuration.
4) What is an Insuclamp cable clamp used for versus a plain two-hole strap?
An Insuclamp is a cable clamp with an insulating element between the steel body and the cable, used to support single conductor or large diameter cable without the metal biting into the jacket or setting up a conductive path at the support. A plain two-hole strap is fine for conduit but is not what you want directly on a large jacketed cable. The B4089ZN is the 4 inch steel version of that clamp.
5) Does the B4089ZN Insuclamp carry a UL listing or other certification for a spec job?
The B4089ZN is supplied as a standard electro-plated steel Insuclamp cable clamp for electrical work. If your drawing calls out a listed or labeled support assembly, match the clamp to what the specifying engineer has approved for that assembly before you commit the run.
