B-Line SB5962313AFB Eaton series open frame racks, Aluminum, #12-24 mounting hardware, Flat black powder coat, Center mount rack mounted shelf, Two mount spaces required, 200 lb load cap., Center mount rack mounted shelf

The SB5962313AFB center mount shelf occupies two mounting spaces on the rack rails, so plan on 2U of vertical panel space. The shelf itself is 2 inches high, 21.5 inches wide, and 13 inches deep.

It mounts with #12-24 hardware, which is the standard thread on Eaton B-Line open frame relay racks with tapped rails. If your rack uses square hole cage nuts (10-32 or M6 clip nuts), you will need the correct nuts and screws for that rail, not the #12-24 set.

Yes. At 21.5 inches wide it spans the full EIA rack frame width, which is the standard footprint for 19 inch equipment mounting on a two-post open frame rack. Confirm your rails are drilled or tapped for #12-24, which is what this shelf ships to use.

It is a center mount shelf. The mounting brackets sit at the middle of the shelf depth, so the 13 inch deep panel is balanced with equipment weight carried on both sides of the rails. A front mount (cantilever) shelf bolts only at the leading edge and is better when you need clear space behind the shelf; center mount is the choice on two-post open frame racks where you want the load centered over the rails.

Aluminum with a flat black powder coat. The powder coat resists scuffing and handles indoor industrial and telecom rooms well; aluminum keeps the shelf itself to 3.8 lb, so you are not spending your 200 lb rack budget on the shelf. For wet or corrosive outdoor exposure, a painted aluminum shelf is not the right pick.

The finish is flat black powder coat, the same finish family Eaton B-Line uses across its black open frame rack line, so it reads as a match next to black rails and black panels rather than a gloss or textured black. If your existing rack is gray or clear anodized, this shelf will not match.
