B-LINE B143YZN – Frequently Asked Questions

1) What does the B-Line B143YZN corner plate actually do in a strut assembly?
The B143YZN is a flat four hole corner plate for Eaton B-Line strut. It lays flat across the face of two strut channels meeting at a corner and bolts through four holes to tie them together in the same plane, so the joint resists racking without a bent angle bracket. It ships pre assembled.
2) What size is the B143YZN corner plate and how thick is it?
It measures .22 x 5.37 x 3.5 inches and weighs .75 lb. The .22 inch dimension is the plate height, so it adds only about a quarter inch of stack behind the bolt head where it sits against the strut face. Check the 5.37 and 3.5 inch footprint against your hole pattern before you order.
3) Do hardware and channel nuts come with the B143YZN, or do I order those separately?
The B143YZN is supplied as a pre assembled plate. Plan on ordering the channel nuts, bolts and washers for the four holes separately, sized to the strut you are using.
4) Is the B143YZN plate steel or stainless, and what is the finish?
Steel with a yellow zinc chromate finish. That plating suits dry indoor runs, mechanical rooms and covered areas. For wet, washdown or exterior work you want a hot dip galvanized or stainless fitting instead, since yellow zinc is a light sacrificial coating.
5) What is the exact part number to order for the B-Line yellow zinc flat corner plate?
Order Eaton B-Line part number B143YZN. The YZN suffix is the yellow zinc chromate finish, so if you need a different plating you are looking at a different suffix on the same B143 plate.
6) Is the B143YZN a UL listed or code rated fitting for electrical support?
No rating or listing is carried on the B143YZN. It is a plain steel strut corner plate for electrical support framing, so where your inspector wants a listed support assembly, verify the rating at the channel and system level rather than at this plate.
