B-LINE B518-4ZN – Frequently Asked Questions
1) What size is the B-Line B518-4ZN junction box?
The B518-4ZN universal junction box measures 7.25 in height, 10 in length/depth and 5.5 in width. Those are the box dimensions to check against your strut run and available clearance before you mount it. It weighs 1.92 lb, so a single strut channel nut and bolt set carries it without issue.
2) Does the B518-4ZN come with a cover, or do I have to order one separately?
The cover is included. Each B518-4ZN ships as one junction box with screws plus one box cover, so you are not buying the lid as a separate line item.
3) What finish is on the B518-4ZN and is it suitable for a damp outdoor location?
Steel with an electro-plated zinc finish. That is a coating intended for dry, indoor and protected industrial locations such as mechanical rooms, plant ceilings and strut runs. For a wet or exposed exterior location you want a listed weatherproof or hot-dip galvanized enclosure instead.
4) What part number do I order for the zinc-plated B-Line universal junction box?
Order by manufacturer part number B518-4ZN, from the Eaton B-Line strut electrical accessories line. The ZN suffix denotes the electro-plated zinc finish. It is sold as a single model, so there are no size or finish options to specify on the order.
5) Can I use this box for pulling and splicing conductors on a strut-mounted conduit run?
That is what it is built for. The B518-4ZN is a universal junction box in the Eaton B-Line strut electrical accessories family, sized at 10 x 7.25 x 5.5 inches, so it works as a pull or splice point on strut-supported conduit. Steel construction with zinc plating keeps it in the same material family as the strut and fittings around it.
