B-Line Eaton series open racks, Double sided, 340 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 65 mounting spaces, Top angle style,

Yes. The SB5862138TG is built as a Seismic Zone 4 network bay open duct rack, so it is the right choice where the structural spec calls for Zone 4 anchorage. It is also UL Listed. Anchoring to the floor (and to overhead ladder rack or duct where the design calls for it) is what makes the seismic rating meaningful on site, so follow the anchorage detail on the drawing.

Rated load is 340 lb. That is the total equipment weight the frame is rated to carry, so tally up your switches, patch panels and cable managers against it before filling all the spaces. The rack itself weighs 151.25 lb empty, which matters for floor loading and for getting it into the room.

The frame provides 65 mounting spaces at a 19 inch width, which is the standard EIA equipment width, so standard 19 inch panels, switches and patch panels bolt straight in. The rails are punched with 12-24 panel mounting holes, so you need 12-24 rack screws, not 10-32 and not M6 cage nuts.

12-24. The mounting rails are punched with 12-24 panel mounting holes, so order 12-24 rack screws and any threaded accessory hardware to match. Mixing in 10-32 screws will cross-thread the rail.

Double sided means the frame is punched and usable for mounting from both sides rather than a single mounting plane, which is what a network bay rack needs when you are landing patch panels on one face and active gear on the other. It is an open frame rack, not an enclosure, so there are no doors or side panels and no locking security.

An open frame rack is the choice when the room itself is secure and you want maximum cable access and passive airflow, which is typical for a telco network bay with overhead duct and ladder rack. The SB5862138TG is open on all sides, with no doors, so if you need locked access, dust control or forced-air containment, specify a closed enclosure instead.

Order Eaton B-Line part number SB5862138TG. That is the double sided, telco gray, 138 inch, 65-space Seismic Zone 4 network bay rack with 12-24 rails.

The finish is telco gray powder coat over steel, the standard color for central office and telecom bay equipment, so it lines up visually with existing telco-gray racks and runway in the same room.

Top angle refers to the angle member across the top of the frame, which gives the bay its top bracing and a surface for tying into overhead cable runway or duct. It is part of why this frame suits an open duct network bay rather than a standalone two-post rack.
