B-Line SB596S23156SSL Eaton series open frame racks, Steel, Silver powder coat, Double sided rack mounted shelf. Heavy duty, solid shelf, four mounting spaces required, Shelves and #12-24 mounting hardware included

The SB596S23156SSL double sided rack mounted shelf occupies four mounting spaces, and it stands 6 inches high. Plan four rack units of clear vertical space when you lay out the rest of the equipment on the frame.

The shelf ships with #12-24 mounting hardware included, so no separate screw pack is needed as long as your rack rails are tapped #12-24. Racks with 10-32 tapped rails or square hole rails with cage nuts will need the matching hardware for that thread instead.

It is a solid steel shelf, not vented. That is the right pick for supporting gear that does not sit on rails, like a UPS, a converter box or test equipment. If you are stacking heat-producing electronics that rely on bottom airflow, a vented shelf is the better choice.

A double sided shelf like the SB596S23156SSL runs the full 30 inch depth and mounts to rails so equipment can be worked from either face, which suits a two post open frame rack in a telecom or MDF room where techs get at gear from both sides. A single sided cantilever shelf only bolts at the front and is meant for lighter items you access from one direction.

Silver powder coat over steel. It matches the silver powder coat finish used across Eaton B-Line open frame rack components, so a shelf added to an existing silver frame will not stand out. If your room is standardized on black racks, this is a visible mismatch.

The shelf weighs 20.8 lb on its own. Worth counting when you are totaling loaded weight on an open frame rack, especially on a two post frame where several shelves plus equipment all bear on the same uprights.
