B-Line Eaton series open racks, Aluminum uprights and steel extension brackets, #12-24 panel mounting holes, Flat black powder coat, Wall-mounted net

Plan for 74.25 inches of vertical space and 30 inches of depth off the wall. That depth is the frame itself, so add room in front for cable bends and patch cords and behind the rack for the extension brackets to stand off the wall surface.

It is a wall-mounted network equipment rack. Steel extension brackets carry the load back to the wall structure, so it needs solid backing, studs, blocking or masonry, rather than bare drywall. There is no floor base, so nothing sits on the slab.

An open frame rack like the SB704237430FB gives you access from all sides and free airflow, which suits a locked closet where the room itself is the security boundary and you are terminating a lot of copper. Go to an enclosed cabinet instead when the gear sits in an open office, a warehouse aisle or anywhere dust, tampering or lockable doors matter, since an open frame offers no enclosure at all.

The rails carry #12-24 panel mounting holes, so you fasten equipment with #12-24 screws directly. No cage nuts are required, unlike a square hole rack. Order your rack screws in #12-24 and confirm your patch panels and shelves use standard 19 inch EIA hole spacing.

The uprights are aluminum to keep the assembly light, 27 pounds for a full height frame, while the extension brackets that transfer the load into the wall are steel for stiffness at the anchor points. That mix is why a two-person crew can hold it up while the anchors go in.

The finish is flat black powder coat, the same low sheen black B-Line uses across its open frame line, so it reads consistently next to existing black racks and ladder rack in the room. Only one finish is offered on this model.
