B-Line Eaton series open racks, Aluminum uprights and steel extension brackets, #12-24 panel mounting holes, Double sided universal, Flat black powde

Plan for a 24 inch depth off the wall face, with the frame measuring 39.25 by 39.25 inches in height and width. Leave clearance in front for patch cord bend radius and on the sides to swing equipment in, since this is an open frame with no side panels or door.

The rack itself weighs 17.4 lb empty, but the wall has to carry that plus the full equipment load, and the frame hangs 24 inches out from the wall, which puts real leverage on the fasteners. Anchor the steel extension brackets into solid framing (studs, plywood backboard) or masonry. Fasteners are not supplied with the rack, so they are specified to suit the wall type.

An open frame rack is bare uprights on brackets: no doors, no sides, no locks. It gives you the best access and passive airflow and it is the cheaper way to get 19 inch mounting in a telecom closet or back-of-house room. An enclosed wall cabinet is what you want where the gear is in a public corridor, a tenant space or a dusty environment and needs to be secured or filtered. The SB704233924FB is the open type, double sided universal, finished flat black powder coat.

Double sided universal means the uprights are drilled on both faces, so you can mount equipment from the front and mount hardware such as patch panels or rear supports from the back side of the same rail. It lets you flip or reverse the mounting orientation to suit how the wall opening and cable entry are laid out rather than being locked to one direction.

#12-24. The panel mounting holes on this rack are tapped #12-24, which is the common thread on North American open frame racks. 10-32 screws will not engage, so order #12-24 rack screws, and order enough for the panels you are hanging since screws are not included with the rack.

Construction is aluminum uprights with steel extension brackets, all in a flat black powder coat. The aluminum uprights handle humidity well; the steel brackets rely on the powder coat, so avoid scratching them during install and touch up any bare metal if you are mounting in a damp or unconditioned space.

At 17.4 lb the rack is a one-person lift, but holding a 39.25 inch frame level against a wall while starting anchors is a two-person job in practice. Common approach is to fasten the extension brackets to the wall first, then set the uprights onto them.
