The B239ZN is a 90 degree offset bent tee fitting for strut channel framing. It has five bolt holes and a bend that carries a branch off at 90 degrees while offsetting it out of plane with the run, so you can tee a second strut member off a main without the two channels fouling each other. It is the fitting you reach for when a straight flat tee would force the branch into the same plane as the run.

No. The B239ZN is an offset bent tee, meaning the branch is deliberately stepped out of the plane of the run. If you want a flat, in-plane 90 degree branch, use a flat tee plate or a 90 degree angle fitting instead. Pick the offset version only when the two members need to sit on different planes or you need the branch to clear the face of the main channel.

It is steel with an electro-plated (zinc) finish, which is a general indoor and dry-to-mildly-damp duty coating. For exterior runs, wash-down areas, parking decks or coastal work, specify a hot dip galvanized or stainless strut fitting instead, since electro-plating is a thin sacrificial layer and will not hold up to sustained wetting.

The B239ZN ships as the fitting alone. Strut hardware is ordered separately, so plan on the matching channel nuts, hex head bolts and washers in a finish that matches the electro-plated fitting for each of the five holes you intend to use. Mixing a plain or zinc bolt into a galvanized run is a common cause of early rust staining.

Order Eaton B-Line part B239ZN. It is a single catalog number with no finish or size options to specify, so there is nothing else to call out on a purchase order beyond quantity.
