B-LINE B390SZN – Frequently Asked Questions
1) Does the B-Line B390SZN swivel box connector come with a conduit reducer?
One 3/4 inch conduit reducer is included with the B390SZN. That means you can run the connector at its full opening or step it down to 3/4 conduit without buying a separate bushing.
2) Is the B390SZN box connector UL Listed for commercial electrical work?
Yes, the B390SZN carries a UL Listed marking, which is what most inspectors and institutional specs look for on a box connector.
3) What does the 360 degree swivel on the B-Line B390SZN actually do for me on an install?
The B390SZN is a 360 degree swivel box connector, so the conduit entry rotates through a full circle relative to the box. On retrofits and tight ceiling spaces that lets you land the conduit at whatever angle the existing run comes in at, instead of forcing an offset bend or repositioning the box.
4) What is the B390SZN made of?
Steel construction. That is the usual choice for a box connector in commercial and industrial runs where a die-cast or plastic fitting would not hold up to handling.
5) Is B390SZN the part number I should order, and is that the manufacturer number?
B390SZN is the B-Line manufacturer part number, ordered as a single model with no size or finish options to select.
