B-Line Eaton series open racks, Double sided, 340 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 58 mounting spaces, Top angle style,

Yes. The SB5866108TG is built as a Seismic Zone 4 network bay open duct rack, so it is intended for the highest seismic design zone. It is fabricated from ASTM A570 grade 33 steel and is UL Listed.

Load capacity on the SB5866108TG is 340 lb. That is the total equipment weight the frame is rated to carry across its 58 mounting spaces, so tally up your switches, patch panels and PDUs before you fill it. The rack itself weighs 138.25 lb empty.

The rails carry 12-24 panel mounting holes, which are tapped threads. No cage nuts or clip nuts are needed, but your equipment has to be mounted with 12-24 rack screws rather than the 10-32 screws older telco gear sometimes ships with.

It stands 108 in tall and provides 58 mounting spaces. At 108 inches it is taller than the common 84 inch two-post rack, so check your ceiling height, overhead ladder rack and any fire sprinkler clearance before you order.

Plan on 23 in for the rack width and 108 in for the length/depth dimension, with an overall height of 108 in. Lay that out against your aisle spacing and anchor pattern before the floor gets cored.

Double sided means the bay is configured for equipment access and mounting from both faces rather than a single front-loaded side. It is a top angle style frame, which is the style used for running overhead cable duct and ladder rack across the top of a lineup of bays.

An open duct rack like the SB5866108TG has no doors or side panels, which gives unrestricted cable access and airflow from both sides and makes it the normal choice for network bay lineups in a secured room. If the equipment sits in a space where physical access has to be controlled, or you need front-to-back airflow containment, an enclosed cabinet is the better pick instead.

Finish is telco gray powder coat over steel, the standard gray used across central office and network bay lineups, so it lines up visually with existing telco frames.

The frame weighs 138.25 lb on its own and stands 108 in tall, so it is a two-person set and stand at minimum. Seismic Zone 4 use also means it has to be anchored to the floor and, in most lineups, braced at the top angle.
