B-LINE SB21508YZ – Frequently Asked Questions
1) What size is the B-Line SB21508YZ two hole plate?
The SB21508YZ two hole plate measures 6.75 by 2 by .38 inches and weighs .32 lb. That 2 inch width matches standard strut face dimensions, so it sits flat across the face of the channel rather than overhanging.
2) Is the yellow zinc finish on this B-Line plate OK for outdoor or damp locations?
Yellow zinc chromate over steel is a mild-corrosion plating meant for dry indoor use. It is not a hot dip galvanized or stainless finish, so for exterior runs, wash-down areas, or corrosive environments you want a hot dip galvanized or stainless version of the same fitting instead.
3) What is a two hole plate used for in a strut support system?
It is a flat steel splice-type fitting with two bolt holes, used as an auxiliary support accessory to tie strut, brackets, or hangers together where you need a simple straight connection rather than an angle fitting. The plate itself is hardware only, so bolts, nuts, and channel nuts are separate line items.
4) Does the B-Line SB21508YZ two hole plate carry a UL listing or other certification?
No certifications apply to the SB21508YZ plate. It is a plain steel support accessory, so if your submittal requires a listed or labeled component, specify that at the assembly level rather than expecting it on this fitting.
5) Is there more than one version of the B-Line SB21508 plate to choose from?
Only the yellow zinc chromate two hole plate, part number SB21508YZ, is offered here. There is no size or hole-pattern choice to make on the order, so ordering is just quantity.
