B-LINE SB576A04YZ – Frequently Asked Questions

1) What does the B-Line SB576A04YZ adapter plate actually do?
It adapts a 23 inch equipment rack to accept 19 inch rack-mount panels and gear. The kit is a pair of steel plates that mount to the 23 inch rails and present standard 19 inch mounting holes, giving you 4 mounting spaces (4 rack units) of usable 19 inch space. Part number SB576A04YZ.
2) How much 19 inch rack space do I get from the SB576A04YZ, and will it hold a 2U switch?
You get 4 mounting spaces, so 4 rack units of 19 inch mounting. A 2U switch fits with 2U left over. The plate measures 6.94 inches on the height dimension, which is the 4U run of hole pattern. If you need more than 4U of 19 inch space in a 23 inch rack, you need multiple sets of plates or a taller adapter.
3) I have a 19 inch rack and 23 inch telecom gear. Will this plate help?
No. The SB576A04YZ works the other direction: it fits a 23 inch equipment rack and gives you 19 inch mounting holes. To put 23 inch gear into a 19 inch rack you need a 19 to 23 inch widening adapter, not this part.
4) Is mounting hardware included with the B-Line 23 inch to 19 inch rack adapter plates?
Yes, #12-24 mounting hardware ships with the plates, so you can fasten them to the 23 inch rails out of the box. #12-24 is the standard thread on B-Line open frame racks and on most 19 inch panels, so the screws you use for your equipment will match the same thread.
5) What is the yellow zinc finish on these B-Line rack adapter plates, and is it okay for a telecom room?
The plates are yellow zinc chromate over steel. That is a plated corrosion-resistant finish for dry indoor use, typical of telecom and IT closet rack hardware. It is not a painted or powder-coated cosmetic finish, so if you need black to match a finished equipment rack in a visible space, this is not the look you want.
6) How heavy and how thick are the SB576A04YZ plates?
The set weighs 1.5 lb. Dimensions are 6.94 in, 2 in, and .13 in across height, depth and width, so the plate stock is thin gauge steel with a 2 inch flange face. It is a light bracket, not a structural shelf, so heavy chassis should still be supported by rails or a shelf rather than hung off the adapter alone.
7) Do the B-Line SB576A04YZ adapter plates carry any listing or certification?
Certifications are marked Not Applicable for these adapter plates. They are unpowered steel mounting brackets, so there is no electrical listing attached to the part itself.
