The rails are tapped for 12-24 panel mounting hardware, so order 12-24 rack screws. Cage nuts are not required, and 10-32 screws will not thread correctly into a 12-24 hole.

Load capacity is 200 lb. That covers patch panels, fiber enclosures and light-to-mid switching, but it is not a rack for loading with heavy full-depth servers or UPS units. Add up the shipping weights of your gear against that 200 lb figure before you commit. The rack itself weighs 103.33 lb.

Yes, it is a Seismic Zone 4 rack, which is the rating specified for the highest-risk seismic areas. Zone 4 performance depends on the rack being anchored to the floor per the seismic detail and, where called for, braced to overhead runway, so budget the anchors and bracing as part of the install.

It is UL Listed, which is what most inspectors and institutional specs want to see on telecom racking in a communications or equipment room. The frame is steel.

An open frame rack like this B-Line duct rack gives you access from all four sides and unrestricted airflow, which is why it is the normal choice in a locked, dedicated telecom or MDF room where physical security is handled by the door. Choose an enclosed cabinet instead when the rack sits in a shared space, a corridor, or a dusty area and the equipment itself needs to be locked up or shielded. This is a two-post open frame with a top channel style, not a cabinet, so it has no doors, sides, or lockable panels.

The finish is a telco gray powder coat, the standard gray used across telecom racking and ladder rack, so it lines up visually with most existing equipment room frames and cable runway. Powder coat over steel also holds up to repeated re-racking without chipping the way wet paint does.
