B-Line Eaton series open racks, Steel, Brushed aluminum, Customer premise style, Two-post network equipment rack, 11 gauge, ASTM A570

UL Listed, yes. That matters for institutional and government specs where every piece of equipment in the telecom room has to carry a listing, and it is stated on the rack itself rather than inferred from the family.

Plan around a footprint of 20-5/16 inches wide by 19 inches deep for the frame itself, with the rack measuring 19 inches on the height/depth figures published for it. Add clearance front and rear for cable management and access, since an open two-post rack is worked from both sides.

The frame is steel formed from 11 gauge material to ASTM A570, the structural sheet steel spec, which is the heavier end of open-frame rack construction rather than a light-duty formed channel. The assembly itself weighs 33 lb.

A two-post open frame like this B-Line rack gives you open access to both sides of every patch panel and the easiest cable routing, which is why it is the standard choice in a locked telecom closet. Choose an enclosed cabinet instead when the equipment sits in an open office, a shared room, or anywhere physical security, dust, or airflow containment is a requirement, since an open frame offers none of those.

Customer premise style is the configuration intended for the building-side telecom or IDF closet, where the owner's network gear terminates, rather than a carrier central office layout. Practically it means an open two-post frame for switches, patch panels and cross-connect hardware in a room you control access to.

The finish is brushed aluminum, which is the lighter grey-silver look rather than the black finish most commonly spec'd on data racks. If the existing frames in the room are black, this one will not match visually, though it mounts the same 19 inch equipment.
