B-Line Eaton series strut fittings and accessories, 5.37" Height, 5.37" Length, 1.62" Width, 1.43lbs, Steel, Five hole tee gusset plate, Electro-plate

It is steel with an electro-plated zinc finish, which is a finish meant for dry indoor service, mechanical rooms, and covered areas. Electroplated zinc is a thin coating and will not hold up the way hot dip galvanizing does in exterior, damp, or corrosive environments. For a rooftop, parking structure, or washdown area, specify a hot dip galvanized or stainless version of the same fitting instead.

It measures 5.37 inches in height, 5.37 inches in length, and 1.62 inches in width, and weighs 1.43 lb. The two equal 5.37 inch legs are what tells you whether it will land inside your strut run: you need that much clear channel on each side of the intersection to seat all five holes.

No. The B532ZN ships as the plate only. You order the strut nuts and hex bolts separately, five sets to make up the full five hole connection, sized to the channel you are tying into. Match the nut and bolt finish to the plate so you are not putting bare steel hardware against a zinc plated fitting.

The manufacturer part number is B532ZN, from the Eaton B-Line strut fittings and accessories line. The ZN suffix is the electro-plated zinc finish. Quote it by that number when you are matching existing fittings on a job so you get the same finish across the run.

Use the gusset version, like the B532ZN, where the tee has to resist twisting or carry a branch load, such as a trapeze support teeing off a main run. The gusset stiffens the corner between the two legs. A flat tee plate is the lighter choice when the joint is only holding alignment or a light conduit branch and you need the plate to sit flush against the channel face with nothing standing proud.

Certifications are marked Not Applicable for the B532ZN. It is a mechanical strut connecting plate, not an electrical device, so it is specified by material, finish, and hole pattern rather than by a listing. If your submittal calls for a certified item, that requirement usually sits with the channel and the raceway, not the gusset plate.
