B-Line Eaton series open racks, Double sided, 340 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 66 mounting spaces, Top angle style,

The rails are tapped with 12-24 panel mounting holes, so equipment mounts with 12-24 machine screws straight into the rail. No cage nuts or square-hole hardware is involved. If your gear ships with 10-32 or M6 screws, order 12-24 screws separately, and check that your panel ears are slotted for 12-24 spacing.

The SB5862140TG is built as a Seismic Zone 4 network bay, meaning the frame is rated for the highest seismic design category used in that older zone scheme. It only performs that way if it is installed as a seismic rack: anchored to the structural floor and braced at the top angle to overhead runway or building structure. A free-standing, unanchored install gives up the seismic rating entirely. It is also UL Listed.

An open frame rack like this double sided B-Line network bay gives access from both sides and integral duct space for vertical cable management, which is what you want in a controlled telecom or MDF room with lots of copper terminations. It gives no physical security, no dust protection, and no directed airflow. If the room is shared, public, or dirty, or the gear needs a sealed air path, go with an enclosed cabinet instead.

The frame weighs 152.53 lb empty and stands 140 inches tall. That is manageable weight but awkward length, so plan on at least two people to walk it in horizontally and stand it up, with overhead clearance to tip it upright. Add the 340 lb equipment rating to the frame weight when you check the floor loading and anchor selection.

Finish is Telco gray powder coat over steel, the standard color used across telecom equipment bays, so it will read as a match alongside existing telco gray racks and runway in the same room. Exact shade matching between manufacturers and production runs is never guaranteed, so put it in the same lineup rather than side by side with a critical color match if that matters visually.

Order model SB5862140TG from Eaton B-Line. That designation covers the double sided, 140 inch, telco gray, top angle style network bay with 12-24 rails and 66 mounting spaces, rated 340 lb.
