B-Line Eaton series open racks, Steel, Telco gray powder coat finish, Top angle style, Seismic Zone 4, open duct unequal flange rack, 11 gauge, ASTM

Yes. The Eaton B-Line SB5567084TG is built as a Seismic Zone 4 open duct unequal flange rack, which is the configuration specified for the highest seismic design category in telecom and data rooms. It is also UL Listed. The frame is 11 gauge steel to ASTM A570, which is the heavier material that makes the seismic rating possible.

The rack stands 84 inches tall and measures 23 inches wide, with a stated length/depth of 84 inches. Plan floor space and overhead clearance around those figures, plus your own aisle and cable access on both sides since it is an open frame with no side panels or doors.

126.5 pounds for the rack itself, before any equipment is mounted. That is a two-person lift and uncrate, and it is the number to start from when you are calculating floor loading or anchor capacity for a seismic install.

An open frame rack like the B-Line SB5567084TG is the right call in a secured telecom or equipment room where you want maximum airflow, easy cable access from all sides, and simple front and rear equipment service. It has no doors, side panels, or lock, so it gives you no physical security and no dust containment. If gear sits in a shared space, a warehouse, or anywhere the public can reach, an enclosed cabinet is the better choice.

Unequal flange means the two legs of the upright channel are different depths, so the mounting flange the equipment bolts to is offset from the structural flange. On the SB5567084TG that gives you a deeper open duct channel behind the mounting rail for vertical cable routing while keeping a standard face for rack-mount gear. It is the common telco rack profile rather than a square-hole cabinet rail.

Top angle style means the rack is fitted with an angle at the top of the uprights, which is what you bolt overhead cable runway or ladder rack to, and what ties the rack into an overhead bracing system. In a Seismic Zone 4 room that top connection is part of how the rack gets braced, so it is worth confirming your runway height before you set the rack.

The frame is 11 gauge steel meeting ASTM A570, which is the heavier structural gauge B-Line uses on seismic-rated racks rather than the lighter aluminum or thin-wall steel used on basic relay racks. That is what lets it carry a loaded equipment stack and hold a Seismic Zone 4 rating.

Telco gray powder coat over steel, which is the standard color used across telecom equipment rooms, so it lines up visually with most existing gray relay rack lineups. If your room is standardized on black, this one will not match.
