B-Line Eaton series open racks, Steel, #12-24 mounting hardware, Three mounting spaces required, 100 lb load capacity, Silver powder coat, Single si

Yes. The Eaton B-Line SB747V2310SSL is a rack mounted shelf built for open frame racks, with a 22.31 inch overall width that spans the standard 19 inch EIA rack rail opening and lands on the rails. It takes up three mounting spaces (3U) of vertical rail, and the depth from the rails back is 10 inches. Height of the shelf assembly is 5.19 inches.

It mounts with #12-24 hardware, which is the thread B-Line open frame racks are tapped for. Mounting hardware of that size is called out with the shelf, so confirm your rack rails are #12-24 tapped and not 10-32 or square-hole cage nut before you order, because the rail thread decides whether these screws thread in.

The shelf is rated for 100 lb. That covers most switches, patch panel gear, media converters, a UPS of modest size, or tools and manuals in an MRO rack. For heavier items, or anything deeper than the 10 inch shelf depth where the load overhangs the back edge, use a four-post or two-post cantilever shelf rated above 100 lb instead.

Plan for three mounting spaces (3U) of clear rail. The SB747V2310SSL shelf is a single sided unit, so it mounts to the front rails only and the 5.19 inch assembly height is what consumes that 3U. If you are laying out a rack elevation, block out 3U plus whatever airflow clearance the gear sitting on the shelf needs.

Solid. The SB747V2310SSL is a solid steel shelf, so it gives a flat continuous surface with no perforations. If the equipment sitting on it dissipates heat downward or you want airflow through the shelf pan, choose a vented rack shelf instead.

Single sided means it attaches to one pair of rack rails, the front pair, and cantilevers back 10 inches. It does not span front to rear rails, so it works in an open two-post relay rack as well as in a four-post cabinet. Because all the 100 lb rating is carried on that one set of rails, keep heavy loads pushed back against the rails rather than out on the front edge.

The shelf is finished in silver powder coat, which is the standard finish on Eaton B-Line open frame racks, so it matches a silver rack frame rather than a black one. If your racks in the building are black, the finish will read as a mismatch even though the fit is the same.

Yes, it is a one-person install. At 8.4 lb the steel shelf is light enough to hold in place with one hand while starting the #12-24 screws. Start the bottom screws on both rails first, let the shelf hang, then fit the top screws.
