B-Line Eaton series open racks, Aluminum, #12-24 mounting hardware, Flat black powder coat finish, Center mount rack mounted shelf, Two mount spaces

The SB5962315AFB center mount shelf is rated for a 200 lb load capacity. That covers most switches, UPS units, and patch gear a network closet needs to sit on a shelf rather than rail-mount. The shelf itself is aluminum and weighs 4.3 lb.

Two mount spaces are required for the SB5962315AFB. Plan two rack units of clear vertical space when you lay out the rack, since the shelf brackets occupy both. Shelf height is 2 in.

Depth on this shelf is 15 in, with a 21.5 in width. That suits switches, media converters, and small UPS or power units. Equipment deeper than 15 inches will overhang the front or rear edge, so for full-depth servers you want a deeper shelf or proper rail kit instead.

It ships for #12-24 mounting hardware, which is the thread B-Line open frame racks are tapped for. If your rack rails are tapped 10-32 or are square-hole cage nut rails, you'll need to sort the hardware to match the rail, not the shelf.

A center mount shelf, like this B-Line model, attaches at the middle of the shelf rather than at the leading edge, so load is balanced across the rack uprights instead of cantilevered off the front. On a two-post open frame rack that is the usual choice for heavier gear. Front-mount shelves are the option when you need the equipment flush to the front of the rack and the load is light.

Order MPN SB5962315AFB from Eaton B-Line. That is the aluminum, flat black powder coat, center mount shelf, two mount spaces, 15 in deep by 21.5 in wide.

Finish is flat black powder coat, which is the standard finish on Eaton B-Line series open frame racks, so it reads the same as black racks and black accessories in the same line. Substrate is aluminum, so it will not rust in a damp basement or mechanical room the way a painted steel shelf can once the coating is chipped.
