B-Line SB5764140TG Eaton series open frame racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 45 mounting spaces, Top channel style, Seismic Zone 4, network bay closed duct rack

Yes. The SB5764140TG is built as a Seismic Zone 4 network bay closed duct rack, which is what a data center or telecom room in a high seismic region needs on the drawing. It is also UL Listed. If your spec calls out seismic anchoring, this is the rack family written for it.

It provides 45 mounting spaces, so you get 45 usable rack units of panel, switch and patch capacity in a single bay. Plan your active gear, patch panels and vertical manager placement against that number before you order a second bay.

Yes. The rails are punched with 12-24 panel mounting holes, so standard 12-24 rack screws thread straight in with no cage nuts. Gear supplied with M6 or 10-32 hardware will need the correct 12-24 screws instead, so order a box with the rack.

The published figures are 140 in height, 140 in length/depth, 19 in width, at 131 lb. Check ceiling height and door clearance on the route into the room before delivery, and plan on rigging help plus a floor anchor pattern for a unit at that weight and height.

A closed duct bay like the SB5764140TG carries an enclosed cable duct as part of the frame, so horizontal and vertical cable runs are routed and contained rather than draped across the face. A plain open frame relay rack is just the two uprights and needs separate managers added. The SB5764140TG also uses a top channel style, which is the arrangement used for runway and ladder rack tie-in overhead.

The finish is a Telco gray powder coat, the standard color used across telecom and central office frames, so it lines up visually with existing Telco gray bays and runway. The frame itself is steel.
