B-Line Eaton series open racks, Aluminum uprights and steel extension brackets, Aluminum - brushed, #12-24 panel mounting holes, 200 lb load capacity

Plan on a 39.25 by 39.25 inch footprint on the wall with 18 inches of depth off the wall face. The frame itself weighs 16 lb empty, so nearly all of the 200 lb rating is available for equipment, but anchor into studs or use masonry anchors rated well above the loaded weight.

Use #12-24 rack screws. The SB704233918AL uprights are drilled and tapped #12-24, so #10-32 hardware will not thread correctly. Order screws and cage-free washers in #12-24 along with the rack; fasteners are not part of the rack itself.

A wall-mounted open frame rack like the B-Line SB704233918AL is the choice when floor space is tight and the load is light: 200 lb total across a 39.25 inch tall frame handles patch panels, a switch or two and a small UPS shelf. If you are stacking servers, heavy UPS units, or need more than 200 lb of capacity or full 42U height, go to a floor-standing two-post or four-post rack instead.

The uprights are aluminum with a brushed aluminum finish, which does not rust, while the extension brackets are steel. In a humid room the aluminum uprights hold up well; watch the steel brackets and their anchors for surface corrosion over time.

Yes, it is an open frame design rather than an enclosed cabinet, so the sides and rear of mounted gear stay exposed for patch cords and power. That also means no door, no lock and no dust protection, so use an enclosed wall cabinet where the space is public or dirty.
