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

Yes. The SB704193918FB is a 19 inch panel mount open frame rack, so any standard 19 inch EIA rack-mount switch, patch panel or UPS panel will land on the uprights. Panel mount holes are tapped #12-24, which is the common thread for rack gear, so you mount directly to the upright with #12-24 screws rather than using cage nuts.

Plan on a footprint of 20.5 inches wide by 39.5 inches high, with 18 inches of projection off the wall. The 18 inch depth is what usually catches people out in a closet or a hallway, so check door swing and any conduit or panel clearance before you pick the wall. The frame itself is light, 13.5 lb, so the load on the wall is almost entirely your equipment.

An open frame rack like the SB704193918FB gives you access from every side and free air movement, which suits a locked telecom closet or an IT room where the room already provides the security. It has no doors, no sides and no locking, so in a public corridor, a classroom, a lobby or a tenant space where hands can reach the gear, an enclosed wall cabinet is the better call. Open frame also makes cable dressing and patch changes much faster.

Uprights are aluminum and the extension brackets that carry it off the wall are steel, finished in a flat black powder coat. That mix keeps the frame at 13.5 lb while the steel brackets take the wall load. Powder coat over aluminum and steel is fine for a conditioned indoor closet or equipment room; it is not a galvanized or outdoor-rated finish, so keep it out of wet or washdown areas.

The SB704193918FB ships as the rack assembly, aluminum uprights with the steel extension brackets. The fasteners into the wall are down to your substrate, so plan those separately: lag screws into wood studs or blocking, through-bolts on stud framing, or concrete anchors on masonry. Anchor to structure, not to drywall alone, because the bracket puts your equipment load 18 inches out from the wall.

One configuration, ordered as part number SB704193918FB: 20.5 inches wide, 39.5 inches high, 18 inches deep, #12-24 tapped panel mount holes, flat black. There is no finish or height option to specify, so the only thing to confirm is that 39.5 inches of wall height and 18 inches of projection work in your space.

It is flat black powder coat, a matte black rather than a gloss, which is the standard finish on most commercial network racks and ladder rack. If you are standardizing a facility on black hardware it will read consistently alongside existing black open frame racks and cable runway.
