B-Line B141PAZN Eaton series strut fittings and accessories, .23" Height, 5.37" Length, 1.62" Width, .55lbs, Steel, Three hole splice plate | Pre assembled, Thickness 1/4 in, Electro-plated

The B141PAZN is a three hole splice plate used to join two lengths of strut end to end, carrying the connection across the joint through three bolted holes. It ships pre-assembled, so the hardware comes with the plate rather than being ordered separately.

The finish is electro-plated zinc, which is an indoor, dry-location finish. For exterior runs, wash-down areas, or anywhere condensation collects, specify a hot dip galvanized or stainless splice plate instead; electro-plating is a thin coating and will rust at cut and drilled edges once it is exposed to weather.

No. The B141PAZN is supplied pre-assembled, so the fastening hardware comes with the plate. That saves picking channel nuts and bolts as a separate line item when you are ordering splice plates by the box for a large strut run.

Quarter inch steel. The material gauge is 1/4 in and the plate is carbon steel, which is the heavier of the common splice plate thicknesses and is what you want where the joint carries load rather than just aligning two sticks of strut.

It measures .23 x 5.37 x 1.62 inches (height, length, width as published) and weighs .55 lb. The 1.62 inch width is the figure to check against your channel face before ordering, since a plate wider than the strut face will foul adjacent runs or conduit clamps.

The part number to order here is B141PAZN, the zinc electro-plated version of the B-Line B141 three hole splice plate. The ZN suffix identifies the plating; base part numbers in the B141 family differ only by finish, so if a drawing calls out a different suffix, it is calling out a different coating, not a different plate geometry.

A three hole splice plate is for joining strut end to end in line, splicing two runs into one continuous length. If you are making a right angle or a tee between two pieces of strut, you want an angle or corner fitting instead. If you are clamping a run to the back of another run without bolting through the slots, that is a splice clamp job, not this plate. The B141PAZN bolts flat against the channel face through three holes over its 5.37 inch length.

It works as a standard in-line splice for indoor strut systems: 1/4 inch steel, zinc electro-plated, three holes, shipped pre-assembled with its hardware at .55 lb per piece. For an MRO crib standardizing on one splice plate, the pre-assembled format is the one that keeps loose channel nuts out of the bin. Keep a galvanized equivalent on hand for any exterior or damp runs.
