B-Line Eaton series open racks, Steel, Telco gray powder coat finish, Siesmic zone 4, Closed duct, 45 mounting spaces, Top channel style, 23"

Yes. The Eaton B-Line SB5561108TG is built as a Seismic Zone 4 unequal flange rack, which is the construction specified for the highest seismic design category telecom and data rooms. It is also UL Listed. Plan on anchoring it to the floor and, where your drawings call for it, tying the top into overhead cable runway or a bracing kit per your seismic detail.

45 mounting spaces on the 108 inch frame. That is the usable equipment area for switches, patch panels and rack-mount UPS gear. Count your panels and managers first: a 45-space frame fills up fast once you allow a space of horizontal cable management between every couple of patch panels.

The finish is Telco gray powder coat over steel, which is the standard shade used across B-Line open frame racks and most central office and telecom room hardware, so it lines up with an existing telco gray lineup. Powder coat on steel also holds up to the scuffing a rack takes during a large cable pull better than a painted finish.

An open frame like the SB5561108TG gives you access from all four sides and free air movement around the gear, which is why it is the normal choice for patching-heavy telecom and MDF rooms in a secured space. Pick an enclosed cabinet instead when the equipment sits in a shared or public area and needs to be locked, or when you need doors for airflow containment. This frame carries no doors or sides; security has to come from the room.

You are ordering the steel frame itself, model SB5561108TG. Budget separately for the items that finish a telecom install: floor anchors sized to your slab, vertical and horizontal cable management, grounding busbar and bonding conductor, overhead ladder runway with the brackets that tie into the top of the frame, and rack screws or cage nuts to suit your equipment.

Published dimensions are 19 inches wide, 108 inches high, with a length/depth figure of 108 inches. For layout, allow full working aisle in front and behind since this is an open frame with no doors, and leave room overhead for cable runway above the top of the frame.
