B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 56 mounting spaces, Overhead supported, 11 gauge, ASTM A10

The SB520096TG is an overhead supported rack, meaning it is braced to the structure above rather than standing free on its own footprint. Plan for overhead bracing or a cable runway attachment as part of the install. The frame itself is 96 inches tall and 23 inches wide, so verify your overhead steel or runway line falls over that footprint before you set it.

The rails are punched with 12-24 panel mounting holes, which is the standard threaded hole pattern used on telecom and network open frame racks. Equipment with standard rack ears bolts straight on with 12-24 screws. If your gear ships with 10-32 or cage nut hardware, you will need to swap to 12-24 screws for this frame.

It gives you 56 mounting spaces over a 96 inch tall frame. That is enough for a full switch stack plus patch fields in a single bay, which is why these get used for MDF and IDF build-outs rather than a short 45-space cabinet.

The frame is steel formed from 11 gauge ASTM A1011SS, and the assembly weighs 80 lb. That is the heavier end of open frame construction, intended for loaded equipment bays rather than light patch-only duty.

Published dimensions are 96 in height, 23 in width, and 96 in length/depth. Use the 23 in width when you are spacing multiple bays along a wall, and confirm your ceiling height clears the 96 in frame plus the overhead support above it.

An open frame rack such as the SB520096TG gives you access from all four sides and unrestricted airflow, which is what you want in a secured telecom or MDF room where the door already provides the security. Go with an enclosed cabinet instead when the gear sits in a shared or public space and needs a locked door, or when you need dust control. This frame is overhead supported, so it also depends on having structure or runway above it, which a freestanding cabinet does not.

Telco gray powder coat is the standard equipment-room gray used across telecom framework, so it lines up with typical cable runway and adjacent rack finishes. It is a powder coat over steel, not paint, so it holds up to handling during equipment changes.
