B-Line Eaton series open racks - Length 39.4375 in, Width 23 in, Height 96 in - Steel

No. The SB508096UFB is a self-supporting relay rack, so the frame stands on its own once anchored to the floor. It is a 96 inch tall Telco style frame in 11 gauge steel weighing 114 lb, so it holds its own load without wall bracing or an overhead ladder rack tie-in. Many installers still tie the top to a runway for seismic or cable management reasons, but structurally the rack does not depend on it.

37 mounting spaces across the 96 inch height. That is the usable panel capacity for switches, patch panels and rack-mount gear. Plan your equipment list against 37 spaces, not the raw 96 inches, since the top and bottom of the frame are not all drilled panel area.

The mounting rails are punched for 12-24 panel mounting holes. Order 12-24 rack screws and cage-free hardware to match; 10-32 screws will not thread into these rails. If your existing gear shipped with 10-32 hardware, buy a 12-24 screw kit before install day.

Footprint works out from a 23 inch width and 39.4375 inch length/depth, with the frame standing 96 inches tall. The 23 inch width is the standard Telco style relay rack dimension, and the roughly 39-7/16 inch depth is what you need to allow front to back plus service clearance on each side. Check ceiling height against 96 inches before you commit, since the rack cannot be cut down.

The SB508096UFB is a 23 inch wide Telco style frame. Telco style racks take 23 inch panels on the rails; standard 19 inch EIA gear needs 19-to-23 inch reducer brackets or adapter panels to mount. If your equipment list is all 19 inch, order the adapters with the rack or choose a 19 inch frame instead.

Yes, it carries a UL Listed marking. For institutional and government spec work that is usually the line item the inspector or the drawing calls out on an open frame relay rack.

An open frame rack like this 37 space, self-supporting B-Line unit gives you all-around access for cabling and free airflow, and it is the cheaper, faster install in a secured room. It gives you no physical security, no dust protection and no door. If the room is locked and only techs get in, the open frame is the right call; if the gear sits in a shared space, a lockable enclosure is.

Flat black powder coat over 11 gauge steel. Powder coat is a tougher, chip-resistant finish than wet paint, and flat black is the standard look in a telecom or MDF room so it matches adjacent B-Line frames and ladder rack. It is an indoor finish, not intended for weather exposure.

At 114 lb for the 96 inch frame, this is a two-person set. Plan for two installers to stand it up and hold it plumb while the base is anchored, and stage the floor anchors before you lift.
