B-LINE B451-3ZN – Frequently Asked Questions

1) What is the B-Line B451-3ZN u-support used for?
The B451-3ZN is a slotted three hole u-support made for B22 strut channel. It cradles the channel and bolts through three slotted holes, so it works as a support bracket where strut needs to be held off a wall or structural member. Steel construction, electro-plated zinc finish, 1.72 lb per piece.
2) Will the B451-3ZN fit strut channel other than B22?
It is built specifically for B22 channel. The u-shape is sized to that profile, so if your run is a different channel width or depth, the support will not seat correctly. Confirm the channel designation stamped on your strut before ordering.
3) How much space does the B-Line B451-3ZN take up on the wall?
Overall it measures 1.62 x 10.37 x 1.62 inches. The 10.37 inch dimension is the length that spans across your mounting surface, and the 1.62 inch figures give you the height and width of the u-section. Worth checking against tight equipment-room clearances before you lay out the run.
4) Is the zinc plating on the B451-3ZN suitable for outdoor or wet locations?
Electro-plated zinc is a thin protective coat intended for dry, indoor service, mechanical rooms, ceiling spaces, and interior equipment rooms. For exterior, damp, or corrosive environments you want a hot dip galvanized or stainless support instead.
5) What makes the three hole version different from the one and two hole u-supports?
The B451 u-supports are built up from the B333 series, one, two, or three holes, with a gusset plate on the back for rigidity. The three hole version gives you the longest bearing surface and the most fastening points, which is what you want when the support carries a heavier channel run or has to bridge wider stud spacing.
6) Does the B451-3ZN come with mounting bolts or channel nuts?
The B451-3ZN is supplied as the support itself. The hardware that fastens it to the structure and the channel nuts or bolts that secure the B22 strut are ordered separately, so size those to your substrate and slot before the crew shows up.
7) What part number should I put on the order for the three hole zinc u-support?
Order Eaton B-Line B451-3ZN. The 3 designates the three hole configuration and ZN the electro-plated zinc finish. It is a single-configuration item, no additional options to specify.
8) Why are the holes on the B451-3ZN slotted instead of round?
Slotted holes give you lateral adjustment when you set the support. On a field install where anchor points or stud centers do not line up exactly with the strut run, the slots let you shift the bracket and still land the fasteners, which saves redrilling.
