B-Line Eaton series open racks, Aluminum material, #12-24 mounting hardware finish, Telco gray powder coat, Low profile rack mounted shelf ventilated

Yes. The SB745V2319ATG is a rack mounted shelf with 19 inches of depth and an overall width of 21.25 inches, so the mounting flanges sit outside the 19 inch rack rails and the shelf body projects 19 inches back into the rack. It mounts with #12-24 hardware, which is the thread B-Line open frame racks are tapped for.

Aluminum, finished in Telco gray powder coat, and it weighs 4.9 lb. That low weight is the main practical difference from a steel shelf of the same size: easier to hang single-handed in a two-post open rack, and less dead load added to the frame.

The shelf deck is ventilated (perforated), so convection air can pass up through it rather than being trapped under a solid pan. For non-rack-mount gear like small switches, media converters, or a UPS sitting loose in an open frame rack, that is the version to pick. A solid shelf is the better choice when you want a flat work surface or need to keep dust and dropped hardware off gear below.

It takes #12-24 screws, which is the tapped thread on B-Line open frame rack rails. If your rack rails are tapped 10-32 or use square hole cage nuts, you will need the matching #12-24 hardware or a rail that accepts it. Order the rack screws separately unless a hardware pack is called out on your order.

It is built for B-Line series open frame racks, which are two-post, so it mounts on the front rails only and cantilevers its 19 inch depth back into the rack. Put heavier equipment weight toward the front rails. For deep or heavy gear in a four-post cabinet, a shelf with rear support rails is the better pick.

Yes, if that rack is the standard Telco gray. The SB745V2319ATG carries a Telco gray powder coat, the same finish used across the Eaton B-Line open frame rack line, so shelves added over time stay consistent in a telecom or MDF room. If your racks are black, the color will not match.
