B-Line Eaton series open racks, Steel, Flat black powder coat, 12-24 panel mounting holes, 45 mounting spaces, Two-post network equipment rack

The SB708193012FB gives you 45 mounting spaces, so 45U of usable panel space on a frame that stands 43.1875 inches tall. That is enough for a couple of patch panel stacks plus switches and a UPS shelf in a telecom closet without going to a full 84-inch floor rack.

Yes. The rack is 19.88 inches wide across the frame with rails punched for standard 19-inch EIA panel mounting, so patch panels, switches and shelves with 19-inch ears bolt straight on. The holes are 12-24 tapped, so you use 12-24 rack screws rather than cage nuts or 10-32 hardware.

Order 12-24 rack screws. The rails on this Eaton B-Line rack are tapped 12-24, which is the heavier of the two common rack threads. If you have a bin of 10-32 screws left from another rack they will not thread in, and forcing them strips the rail. Mounting hardware for your panels should be specified separately.

A two-post open frame like this one is the right call when the equipment is already in a secured room and you want free air movement plus access to both sides of every panel for cabling. It carries gear by the front ears only, which suits patch panels, rack-mount switches and shelf-mounted appliances. Choose an enclosed cabinet instead if you need locked doors, dust control, or if you are mounting deep, heavy servers that require four-post rail support.

Footprint is driven by the 12-inch frame depth and the 19.88-inch width, and the frame stands 43.1875 inches tall. Because it is an open two-post design, plan working clearance front and rear for cable dressing and for the depth of anything you hang on it, since equipment will overhang the 12-inch rails.

Yes, the rack is UL Listed. That is the relevant listing for institutional and municipal specs that require listed rack and enclosure products in communications rooms.

Order Eaton B-Line model SB708193012FB. That number covers the steel two-post open frame with 45 mounting spaces, 12-24 tapped rails and flat black powder coat finish, and it is the single configuration, so there is no finish or height option to specify.

Steel frame with a flat black powder coat. The powder coat holds up to handling during install and to the traffic an MRO closet sees, and the matte black matches the typical black patch panel and cable management hardware already in most closets.

The frame weighs 32 lb bare, so one tech can carry and stand it. Assembly and anchoring are still easier with two people because the frame is 43.1875 inches tall and wants to be held plumb while the base is fastened down. Anchors for your floor type are not part of the rack.
