B-Line SB5868096UTG Eaton series open frame racks, Double sided, Steel, Telco gray powder coat, 12-24 panel mounting holes, 51 mounting spaces, Top angle style, Seismic Zone 4, network bay closed duct rack, ASTM A570 grade 33 steel

The SB5868096UTG uses 12-24 tapped panel mounting holes on its rails, so standard rack screws in 12-24 thread go straight in without cage nuts or clip nuts. It gives 51 mounting spaces of usable height, which is what you plan your patch panels and switches against. Anything prepped for 10-32 or M6 hardware needs different screws.

Plan for a footprint 23 inches wide by 96 inches in length/depth, and 96 inches of height. The 96 inch height means you need clear ceiling and, in most rooms, a ladder rack or cable tray run above it, so check for sprinkler heads and low soffits before you set the base. The frame weighs 130.51 lb bare, before any equipment load.

Yes. The SB5868096UTG is built as a Seismic Zone 4 network bay closed duct rack, which is the rating California and other high seismic jurisdictions look for on a telecom bay. It is also UL Listed. Zone 4 rating applies to the rack itself; the floor anchorage and any top bracing to the ladder rack still has to be installed per the engineer's detail.

Double sided on this bay means it is configured for mounting from both faces rather than a single front rail set, which is how telco bays get used for front equipment and rear cross-connect or duct work. It is an open frame design, not an enclosed cabinet, so there are no doors or side panels and cable access is from every side.

An open frame bay such as the SB5868096UTG is the right call in a dedicated, secured telecom or MDF room: cable access on all sides, easier terminations, and no door clearance to plan for. Pick an enclosed cabinet instead when the gear sits in a shared or public area and needs physical security, or when you need dust control or forced airflow. This one has no doors or panels at all.

The finish is a telco gray powder coat, the standard color used across telecom equipment bays, so it lines up visually with existing telco gray lineups. Powder coat over steel also holds up better to handling and equipment sliding in and out than a wet paint finish.

The bay is fabricated from ASTM A570 grade 33 steel, a hot-rolled structural sheet steel with a 33 ksi minimum yield. That is the material spec to cite if a structural engineer is reviewing the seismic anchorage calculation for the bay.

Top angle refers to the angle member across the top of the frame, which is what you bolt ladder rack or cable runway to and what carries the top seismic bracing on this Zone 4 bay. If your design brings runway in overhead, the top angle is the attachment point and it is part of the rack as supplied.
