Yes. The SB5864138TG is built as a Seismic Zone 4 network bay closed duct rack, so it is intended for data and telecom rooms where the structural spec calls for zone 4 anchorage. It is also UL Listed.

The mounting rails are drilled and tapped with 12-24 panel mounting holes, so 12-24 rack screws thread straight in. No cage nuts or clip nuts are needed. Equipment supplied only with M6 or 10-32 hardware will need 12-24 screws instead.

65 mounting spaces is the usable rail capacity on this B-Line rack, measured in standard 1.75 inch rack units. That is well beyond a conventional 45U floor cabinet, which is what the 138 inch overall height buys you in a telecom bay.

Stated as 138 inches high, 19 inches wide, 138 inches length/depth, and 151.25 lb. At 138 inches tall, check your finished ceiling height and any cable tray or sprinkler runs before you commit, and plan on two people plus lifting gear to stand it up.

An open frame rack is the choice for a secured telecom or MDF room where access from both sides and open airflow matter more than physical security. This one is double sided, so equipment and cable management are reachable front and back with nothing to unlatch. If the gear sits in a shared or public space and needs to be locked away or dust protected, an enclosed cabinet with doors is the better call.

Steel with a telco gray powder coat, which is the standard gray used across central office and telecom bay equipment, so it lines up visually with existing B-Line telco frames and ladder rack in the same room.

Top angle refers to the angled bracket at the head of the frame, which is what you land overhead ladder rack or cable runway on and what ties the bay back to the structure. It is part of how a seismic bay gets braced top and bottom rather than only anchored at the floor.
