B-Line Eaton series open racks, Steel, Telco gray powder coat, Double sided rack mounted shelf. Heavy duty, solid shelf, Four mount spaces required,

Four mounting spaces. The Eaton B-Line double sided rack mounted shelf is 6 inches tall, so plan on four rack units of clear space between your equipment when you lay out the rack.

No. The SB596S23153STG ships with the shelf and #12-24 mounting hardware, so you can mount it to a tapped 12-24 open frame rack without sourcing screws separately.

It measures 30 in depth, 23.31 in width, and 6 in height, and weighs 20.8 lb empty. The 30 inch depth is the number to check first: a double sided shelf hangs off both front and rear rails, so your open frame rack has to be set up for that depth before the shelf will land.

Solid. The B-Line SB596S23153STG is a heavy duty solid steel shelf, so it gives you a flat continuous surface for gear that does not bolt to the rails. If you are stacking equipment that dumps heat downward or needs airflow through the shelf deck, a vented shelf is the better choice.

A double sided shelf mounts to both the front and rear rails of an open frame rack, so the load is carried at four points rather than cantilevered off the front two. That is what lets the B-Line SB596S23153STG be rated heavy duty. A front-mount only shelf is fine for a light piece of gear in a shallow rack; for deeper, heavier equipment in a two-post or four-post open frame, the double sided version is what you want.

It is finished in Telco gray powder coat over steel, the standard finish on Eaton B-Line series open frame racks, so it matches B-Line relay racks and other B-Line accessories in the same family. If your existing racks are black or a different manufacturer's gray, expect a visible difference.
