The SB5766108TG is a 108 inch tall open frame rack with 48 mounting spaces, so you get 48 usable rack units of equipment height on a single bay. That is the tallest common telecom bay height, so check ceiling clearance and any overhead cable ladder before you set it.

Yes. The SB5766108TG is built as a seismic zone 4 network bay open duct rack and is UL Listed. It is a 6 gauge steel frame, heavier than a standard equipment rack, which is what carries the seismic load. Anchoring to the slab and to overhead bracing per your engineer's detail is still part of the install.

The rails are punched with 12-24 panel mounting holes, which means you mount gear with 12-24 rack screws. Most switches, patch panels and rack shelves in a telecom bay ship with or expect 12-24 hardware. If your equipment came with 10-32 screws they will not thread into these rails, so order 12-24 screws to match.

Plan for a footprint based on 23 inches of width and a 108 inch length/depth dimension on the frame, and a 130 lb rack weight before any equipment goes in. Because it is an open frame rather than an enclosure, you also need working clearance on both sides for cable dressing and rear access.

An open duct rack like the SB5766108TG gives you access from all four sides and free airflow, and it accepts overhead cable runway and vertical duct directly. That is the usual choice in a secured telecom or MDF room where physical access is already controlled. Pick an enclosed cabinet instead when the equipment sits in a shared or public space and needs a locking door, or when you need to contain airflow.

The finish is Telco gray powder coat over steel, the standard color for central office and telecom bay lineups, so it lines up visually with existing Telco gray racks and runway. The top angle style also matches the way most existing bays take overhead ladder rack.

Top angle means the rack is finished at the top with a horizontal angle across the frame rather than a flat plate or cap. That angle is what you bolt the overhead cable runway or ladder rack support to, so on a 108 inch bay the runway ties into the top of the frame rather than being supported off the wall.
