12-24. The mounting rails on the SB5761108TG are punched for 12-24 panel mounting holes, so order 12-24 rack screws and cage-free hardware. Equipment shipped with 10-32 screws will not thread into these rails.

The SB5761108TG is built as a seismic zone 4 network bay open duct rack, which is what a hospital, data center or public building in a high seismic area will call for on the drawing. It is also UL Listed. Anchoring to the slab and any overhead bracing still has to follow the structural engineer's detail for the room.

126 pounds bare. That is a two-person lift to stand up and plumb, and it is before any equipment, vertical managers or cable load. For a seismic zone 4 anchor, size the floor hardware for the loaded weight, not the 126 pound frame weight.

An open duct rack like the SB5761108TG gives you access from all four sides and unrestricted airflow, which is why telecom rooms and MDF/IDF spaces use them for patch panels, fiber housings and switches. You give up physical security and dust control. If the equipment is in a shared or public space, or the client wants lockable doors, a fully enclosed cabinet is the right call instead. The top channel style on this frame is there to tie into overhead cable runway.

Steel to ASTM A570 grade 33, finished in Telco gray powder coat. Telco gray is the standard equipment-room color, so it matches existing racks, ladder rack and cabinets in most telecom and MDF rooms rather than standing out as a mismatched black frame.
