B-Line Eaton series open racks, Self squaring with tapped assembly holes, Double sided, Steel, Brushed aluminum, 12-24 panel mounting holes, 41 mount

41 mounting spaces on a 96 inch tall frame. That is usable panel space for switches, patch panels and rack-mount gear at standard 19 inch width. If you are planning a network bay, count your panel RU plus any blanks and cable managers against that 41 before committing.

Yes. The frame is 19 inches wide with 12-24 tapped panel mounting holes, so 19 inch EIA gear mounts directly with 12-24 screws. No cage nuts or square-hole clips are needed, and none are required for the job. If your equipment ships with 10-32 hardware, source 12-24 screws to match the rail tapping.

It is built as a Seismic Zone 4 network bay open duct rack, and it is UL Listed. That is the application Eaton states for it, so it suits data rooms in high seismic areas where an ordinary open frame would not be accepted. The anchoring to the slab is still the installer's responsibility and follows the structural drawings for the room.

Double sided here means the rack has mounting rails accessible and tapped for equipment from both faces, so you can load gear front and rear on the same bay. It suits a network bay where switches face one aisle and patch fields face the other. If you only ever mount from one side and want the cheapest frame, a single sided two-post rack does the same job with less steel.

An open frame such as this 96 inch B-Line bay gives you the fastest cable access and best natural airflow, which is why it is the standard choice in a telecom or MDF room with controlled access. It gives you no physical security and no dust protection. If the equipment sits in a shared space, a warehouse, or anywhere the public can reach it, specify an enclosed cabinet with lockable doors instead.

It ships as a frame to assemble, and the assembly holes are tapped and self squaring, so the uprights and base pull into alignment as you torque the hardware rather than needing to be shimmed and measured. At 36 lb the frame is a one or two person lift before anchoring.

Steel, specifically ASTM A570 grade 33, finished in brushed aluminum. It is a top angle style frame. The brushed aluminum finish is a common spec in telecom rooms where multiple bays are lined up and need to match visually across an existing installation.
