B-Line SB5762096TG Eaton series open frame racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 43 mounting spaces, Seismic Zone 4, open duct unequal flange rack, ASTM A1011SS

The SB5762096TG gives 43 mounting spaces on a 96 inch tall frame. At 19 inches wide it takes standard 19 inch rack-mount equipment, so 43 spaces is what you have to budget across switches, patch panels and rack-mount UPS before you need a second frame.

Rails are punched with 12-24 panel mounting holes, so equipment mounts with 12-24 machine screws, not with cage nuts and M6 like a square-hole server cabinet. If your gear ships with cage nut hardware, you will need to order 12-24 rack screws separately.

It is built as a Seismic Zone 4 open duct unequal flange rack, which is the highest of the legacy seismic zones and what specs for California and other high-seismic jurisdictions typically call out. It is also UL Listed. Anchoring to the slab per the structural drawings is still your responsibility on site.

Unequal flange means the two legs of the channel differ in width, giving one deeper face for anchoring and cable support while the other carries the mounting holes. The open duct design leaves the sides and back fully open, so it is for telecom and network rooms where you run cable in from vertical managers and ladder rack overhead. If you need locking doors, side panels or airflow containment, an enclosed cabinet is the right product instead.

Frame dimensions are 96 x 96 x 19 inches as listed for height, length/depth and width, and the rack itself weighs 120 lb empty. Add your equipment weight on top of that when you check floor loading and plan the anchor layout.

Order part number SB5762096TG. That single number covers the 96 inch tall, 19 inch wide Telco gray Seismic Zone 4 open duct frame with 12-24 holes and 43 spaces, so there are no separate height or finish options to specify.

The finish is Telco gray powder coat, the standard telecom equipment gray used across most central office and MDF hardware, so it lines up with existing B-Line and other Telco gray frames and cable managers. It is a powder coat over steel, not paint, so it holds up to equipment being slid in and out.

Steel to ASTM A1011SS, the hot-rolled structural sheet and strip spec, finished in Telco gray powder coat. That designation plus the UL Listing is usually what a submittal package on a network room rack needs.
