B-Line Eaton series open racks, Aluminum uprights and steel extension brackets, Aluminum - brushed, Wall-mounted network equipment rack. Heavy duty,

Plan on a footprint of 20.5 inches wide by 25.5 inches high, with 18 inches of projection off the wall. Add clearance in front for patch cords and behind the gear for bend radius, and remember the depth number is the rack itself, not the equipment hanging past it.

A wall-mount open frame like the SB704192518AL is the right call when floor space is tight and the load is a handful of switches and patch panels. It hangs the 19 inch panel mount rails off the wall, leaving the floor clear. Go floor-standing instead when you are stacking heavy UPS units or servers, or when you need more than the 25.5 inches of vertical mounting height this frame gives you.

The frame itself weighs 10.2 lb, so it is a one-person lift. The load is the issue, not the rack: once populated with switches and patch panels the whole assembly has to be anchored into studs, structural blocking or a masonry wall with appropriate anchors. Wall anchors are sized to your wall type and are not part of the rack.

Order Eaton B-Line model SB704192518AL. That is the brushed aluminum, heavy duty, 19 inch panel mount wall-mounted open frame rack with aluminum uprights and steel extension brackets. There is a single configuration under that number, so no finish or size suffix to add.

Open frame. The SB704192518AL gives you exposed 19 inch mounting rails with no doors, side panels or roof, which is what you want for cable access and passive cooling in a closet. If the equipment needs to be locked away or kept out of dust in a public area, an enclosed wall cabinet is the better choice.

Construction is aluminum and steel: aluminum uprights with steel extension brackets, finished in brushed aluminum. The aluminum uprights won't rust, but the steel brackets are a painted or plated ferrous part, so in a consistently wet or washdown area they are the component to watch.
