The SB596S23153ATG is a rack mounted shelf 23.31 inches wide overall, which is the aluminum relay-rack width rather than a 19 inch EIA panel width. It mounts to the rack uprights and takes up four mounting spaces of vertical height in the rack. If your frame is a 19 inch EIA rack, this shelf is wider than that panel opening and you want a 19 inch rack shelf instead.

Plan on four mounting spaces of rack height for this shelf. The shelf itself is 6 inches high, so in a loaded relay rack you need 6 inches of clear vertical room plus whatever clearance the equipment above and below needs.

#12-24 mounting hardware ships with the shelf, so nothing extra is needed to hang it on a rack with #12-24 tapped rails. If your uprights are tapped 10-32 or use square-hole cage nuts, you will need your own fasteners for that thread.

A double sided shelf mounts to the rails on both faces of an open frame relay rack, so it spans front to back and is supported from both sides. That is what lets it carry equipment loaded from either side of the rack, which is normal in a telecom frame that is accessible front and rear. A single sided shelf cantilevers off one face only and is for equipment loaded from the front. This one is the double sided, heavy duty, solid shelf version, 30 inches deep.

At 30 inches of depth, this shelf projects well beyond the footprint of a typical open aluminum relay rack frame, which is only a few inches deep front to back. Check your aisle clearance both sides before committing, and confirm the frame is floor and overhead braced for the added cantilever load. Overall the shelf runs 23.31 inches wide by 30 inches deep by 6 inches high.

Solid deck, not vented. It is the heavy duty solid shelf version, so it will hold flat-bottom gear like batteries, power supplies, or test sets without anything falling through, but it does not pass air up through the deck. For equipment that draws cooling air from below, use a vented rack shelf instead.

Aluminum construction with a telco gray powder coat, the standard gray used across Eaton B-Line open frame relay racks and accessories, so it matches existing telco-gray frames and panels in a central office or MDF room. Aluminum also keeps the weight down at 7.2 pounds for the shelf itself.

Order it as Eaton B-Line SB596S23153ATG. That is the complete designation, covering the aluminum double sided solid shelf, 23.31 inches wide, 30 inches deep, in telco gray powder coat. There is one configuration, so nothing else has to be specified on the order.
