B-Line Eaton series open racks, Steel, Telco gray powder coat finish, 12-24 panel mounting holes, 45 mounting spaces, Top channel style, Seiemic zone

The SB5552096TG gives you 45 mounting spaces on a frame 96 inches high, so it is a 45U two-post rack in a standard 7-foot-plus footprint. Panel space is 19 inches wide, which is the standard EIA equipment width, so switches, patch panels and rack-mount servers built to 19 inch flanges drop straight in.

Rails are tapped 12-24 panel mounting holes. That means equipment and patch panels bolt directly with 12-24 rack screws, no cage nuts or square-hole hardware. If your gear came with 10-32 screws or you have a stock of 10-32 hardware, you will need to buy 12-24 screws to match this frame.

Yes. The SB5552096TG is built as a seismic zone 4 network bay open duct rack, and it is UL Listed. It is the version to specify where the structural drawings call for seismic anchorage rather than a standard non-seismic relay rack. Anchorage to the slab still has to follow the project's seismic detail.

An open frame rack like this B-Line network bay is the right choice inside a secured, dedicated telecom or IDF room: you get access from all sides for cabling and moves, and heat sheds freely with no fans needed. Pick an enclosed cabinet instead when the gear sits in a shared space, a corridor or a warehouse and you need lockable doors, dust control or air containment. This frame is open steel with no doors or side panels, so it offers no physical security on its own.

Top channel means the frame is finished with a channel across the top of the two uprights. That is the surface installers use to land overhead cable runway or ladder rack and to tie the rack to the ceiling bracing, which matters on a seismic zone 4 bay. If your design has no overhead runway, a top channel frame still works fine standing alone once anchored.

Order Eaton B-Line part number SB5552096TG. That covers the steel 45-space, 96 inch, 19 inch wide open frame with 12-24 tapped rails, top channel, Telco gray powder coat, seismic zone 4 network bay configuration.

The finish is Telco gray powder coat, which is the standard color used across telecom bays and cable runway, so it lines up visually with most existing rooms. Powder coat over steel also holds up better to cart knocks and rack-screw wear than a wet-painted frame.

The frame weighs 89 lb and stands 96 inches. Empty it is a two-person lift to stand upright and walk into position, mostly because of the length rather than the weight. Plan on anchoring it to the floor before loading equipment, since a 45-space two-post frame is top-heavy once populated.
