B-Line B120ZN Eaton series strut fittings and accessories, 3.93" Height, 3.5" Length, 1.62" Width, 1.10lbs, Steel, Six hole double corner angle, 90 deg, Thickness 1/4 in, Electro-plated

The B120ZN is a six hole double corner angle bent at 90 degrees, used to tie two runs of strut channel together at a right angle. Three holes land on each leg, so you get six bolted connection points across the joint instead of the two or three a single-hole bracket gives you. Typical use is corner framing for pipe racks, trapeze supports, and equipment stands built out of strut.

The B120ZN carries an electro-plated zinc finish. That is a thin protective plating meant for dry indoor service. For exterior runs, wash-down areas, or corrosive environments, specify a hot dip galvanized or stainless version of the fitting instead.

No. The B120ZN is supplied as the steel angle alone. You order the strut nuts, bolts, and washers separately, sized to your channel, and you need enough sets to fill the holes you intend to use on each leg.

1/4 inch steel. That is a heavy plate thickness for a strut fitting, which is why the piece weighs 1.1 lb despite being small, and it is the reason this style of angle gets specified on load-carrying corners rather than light bracing.

It measures 3.93 x 3.5 x 1.62 inches (height x length/depth x width), in 1/4 inch steel. Worth checking those numbers against your channel run before ordering, because a double corner angle has to clear the adjoining strut and any hardware already bolted at the corner.

A single two or four hole angle is fine for light bracing or holding alignment. The B120ZN's six holes, three per leg in 1/4 inch steel, spread the load over more fasteners and resist rotation at the joint, which is what you want on a corner carrying pipe, conduit racks, or mounted equipment. If the corner is purely locating a member and takes no load, a lighter bracket will do the job with less bulk.

Order it as B120ZN, from the Eaton B-Line strut fittings and accessories line. The ZN suffix signals the electro-plated zinc finish, so if a drawing calls for a different finish on the same angle, that suffix is the part of the number that changes.
