B-Line SB5856096TG Eaton series open frame racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 51 mounting spaces, Top channel style, Seismic Zone 4, network bay open duct rack, Grade 33, ASTM A570

Yes. The SB5856096TG is a 23-inch-wide open frame rack with 51 mounting spaces and 12-24 tapped panel mounting holes, which is the standard thread for 19-inch EIA panel mounting. The extra width over 19 inches is the rack's own flange and duct structure, so switches, patch panels and rack-mount servers with standard EIA ears land on the rails normally.

It is built as a Seismic Zone 4 network bay open duct rack, and it is UL Listed. Seismic performance still depends on the floor anchorage and any top bracing being installed per the engineer's detail for the room, but the frame itself is the seismic-rated version rather than the standard-duty frame.

Plan on ordering mounting hardware with it. The rails come tapped with 12-24 panel mounting holes, so you need 12-24 machine screws (and washers if your panels call for them) to hang equipment. Cage nuts are not needed because the holes are already threaded.

Top channel is the style of this rack's upper structure, giving you a continuous channel across the top of the 96-inch frame to tie racks together in a row and to attach overhead cable runway or bracing. It is what makes this frame suited to a lined-up network bay rather than a single standalone rack.

The frame is steel to ASTM A570 Grade 33, a structural-quality hot-rolled sheet with a 33 ksi minimum yield, which is the grade Eaton B-Line uses for its seismic-rated bays. That is the load-bearing basis for the frame; distribute heavy items like UPS units low in the 51 mounting spaces and anchor the rack to the floor.

An open duct rack such as the SB5856096TG gives you all-sides access and the easiest cable routing, which is why it is the norm for patch fields and switch stacks in a controlled, access-restricted telecom room. It provides no physical security, no dust protection and no door-mounted airflow containment. If the equipment sits in a shared space, a warehouse, or needs to be locked, specify an enclosed cabinet instead.

It is one open frame bay, model SB5856096TG, supplied as the frame with tapped 12-24 rails. There are no side panels, no doors and no shelves. Vertical cable managers, ladder rack, power strips and mounting screws are separate items you add to complete the install.

The rack weighs 84.87 lb, so two people can carry and stand an 8-foot frame without a lift. Weight aside, the 96-inch height makes it awkward to walk upright through doorways, so most crews move it flat and raise it in the room.

The SB5856096TG is finished in telco gray powder coat, the standard gray used across telecom and network bay hardware, so it lines up with existing telco gray relay racks and cable runway in most equipment rooms. If your existing bays are black, the color will not match.
