B-Line Eaton series open racks, Double sided, 340 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 50 mounting spaces, Top angle style,

It is built as a Seismic Zone 4 network bay open duct rack, which is what a data center or telecom room in a high seismic region needs. It is also UL Listed. Seismic performance depends on anchoring the base to the slab per the structural drawings, so treat the floor anchorage as part of the install scope.

Load capacity is 340 lb of equipment. That is a real constraint for anyone loading a full bay of servers or UPS gear, so total the equipment weights before you fill all 50 spaces. The rack itself weighs 131.89 lb.

Double sided means equipment can be mounted from either face of the frame, so you get front and rear access on an open bay instead of a single-sided wall rack arrangement. The top angle style gives a flat angle at the crown for attaching overhead cable runway or duct, which is how these network bays get tied into a row.

An open duct rack like this one gives unrestricted airflow, the cheapest cable access, and both faces usable for mounting. Pick it for telecom and network bays in a secured room. If the space is shared, publicly accessible, or dusty, or you need locking doors and per-cabinet containment, an enclosed cabinet is the better call. This frame has no doors or side panels.

No cage nuts. The rails come with 12-24 panel mounting holes, so you fasten with 12-24 rack screws. Any equipment shipped with 10-32 or M6 hardware will need 12-24 screws instead, and gear with square-hole-only brackets will not thread into this rail.

Steel, specifically ASTM A570 grade 33, finished in telco gray powder coat. That is the standard finish for central office and network equipment rooms, so it matches existing telco-gray bays and runway in most facilities.
