B-Line Eaton series strut fittings and accessories, 2.25" Height, 2.25" Length, 1.62" Width, .41lbs, Aluminium, Two hole corner angle, 90 deg, no twis

The B231AL is a two hole corner angle fitting for Eaton B-Line strut. It ties two runs of strut together at a fixed 90 degree corner, with one hole in each leg for the strut nuts and bolts. It is a no twist angle, meaning both legs sit in the same plane rather than being offset, so it joins strut framing that meets flat at a right angle.

The fitting measures 2.25 in height by 2.25 in length by 1.62 in width. The 1.62 in width is the dimension to check first, since it needs to sit within or across the face of your strut channel. The 2.25 in legs give you the reach from the corner to each bolt hole.

It ships pre assembled, so there is nothing to build up at the opening. Plan on supplying your own strut nuts and bolts sized to the channel you are fastening into; the angle itself is a two hole bracket and the fasteners are the separate piece of the order.

Use the no twist version, like the B231AL, when both pieces of strut lie in the same plane and meet flat at 90 degrees, such as squaring up a rectangular frame face on. A twisted angle is the one you want when the second run turns out of plane, for example a horizontal strut branching off a vertical run at a right angle in a different axis. Picking the wrong one leaves the bolt holes fighting the channel face.
