B-Line SB5962319STG Eaton series open frame racks, Steel, #12-24 mounting hardware, Telco gray powder coat, Two mount spaces required, 200 lb load capacity, Center mount rack mounted shelf

Plan on two mount spaces (2U) for the SB5962319STG. The shelf panel itself is 2 inches high, which is why it consumes two rack unit positions rather than one. Lay out your rack elevation with that in mind before you commit adjacent gear positions.

Rated at 200 lb load capacity. That covers most switches, UPS units, patch equipment and non-rackmount boxes you would set on a shelf, but weigh the gear before loading it, and remember the shelf hardware itself adds 15.6 lb to the rack.

The SB5962319STG is supplied with #12-24 mounting hardware, which is the thread used on B-Line open frame relay racks with tapped rails. If your rack rails are tapped 10-32 or use square-hole cage nuts, the supplied screws will not thread in and you'll need the matching fasteners for your rail.

Yes. It is built for the Eaton B-Line series open frame racks and mounts to 19 inch rails, with 19 inches of usable depth and an overall width of 21.5 inches across the mounting flanges. Check that you have roughly 21.5 inches of clear side-to-side space, which is normal for an open two-post relay rack but can be tight inside a narrow enclosed cabinet.

Center mount means the shelf's mounting flanges are set back so the 19 inch platform is balanced across the rails rather than cantilevered off the front. On a two-post open frame rack that puts the load over the posts, which is what you want for heavier gear up to the 200 lb rating. If you need the equipment face flush with the front of the rack instead, a front-mount shelf is the better choice.

Order it as Eaton B-Line SB5962319STG. That single part number covers the steel center mount shelf in telco gray with the #12-24 hardware included, so there are no separate finish or hardware options to specify.

It ships in telco gray powder coat, the standard finish on B-Line telco relay rack product, so it lines up with existing gray open frame racks and gray accessories in the same room. Steel construction with a powder coat means it holds up in a normal conditioned equipment or MDF room. If your racks are black, this shelf will not match.
