B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 49 mounting spaces, Top angle style, Seismic Zone 4, open

Yes. The SB5769084TG is built as a Seismic Zone 4 open duct unequal flange rack, so it is intended for the highest seismic design category installations. It is also UL Listed. The frame is 11 gauge steel to ASTM A1011SS, which is what gives it the stiffness for seismic anchoring.

The rails are punched with 12-24 panel mounting holes, so you need 12-24 rack screws. There is no tapped 10-32 option on the SB5769084TG, and cage nuts are not used, the holes are threaded for 12-24 directly.

Plan on a 23 inch wide footprint and 84 inches of vertical clearance. Height and length/depth are both listed at 84 inches. In practice you also want front and rear working clearance on an open frame rack, since cabling and equipment are accessed from both sides.

The rack weighs 118 lb bare. That is a two-person lift to stand up and hold plumb while the base is anchored, before any equipment goes in.

An open frame rack like the SB5769084TG suits secured telecom rooms and MDF/IDF closets where you want full access to cabling from all sides and passive airflow, with no doors or side panels to work around. Go with an enclosed cabinet instead if the equipment sits in a public or shared space and needs to be locked, or if you need contained airflow and dust control. This one is the open, unequal flange style with a top angle for overhead cable runway attachment.

Telco gray powder coat over steel, which is the standard color for B-Line telecom frames and cable runway. If your existing frames and ladder rack are B-Line telco gray, this matches the fleet.

The top angle is the horizontal member across the head of the frame. It ties the two uprights together and gives you a bolting surface for cable runway, overhead ladder rack, or a wall/ceiling brace kit. On a tall 84 inch open frame that overhead tie-off is normally how the rack gets braced at the top in addition to floor anchoring.
