B-Line Eaton series open racks, Double sided, Steel, Telco gray powder coat, Two mounting spacing styles available, Top angle style, Seismic Zone 4,

Yes. The Eaton B-Line SB5869108TG is built as a Seismic Zone 4 network bay closed duct rack, which is what data centers and central offices in high seismic regions specify. It is also UL Listed. Zone 4 rating depends on the rack being anchored per the seismic detail, so the floor anchorage and any overhead bracing still have to be part of the install.

Width is listed at 23 inches and depth at 108 inches, with a product weight of 138.25 lb. That weight is the bare frame only, loaded with switches, patch panels and cable it climbs fast, so size the floor loading and the anchors for the populated rack, not the shipped weight.

Double sided means the rack has mounting rails on both faces, so you can hang equipment front and rear off the same bay rather than one side only. That is the configuration used for network bays where patch fields sit on one side and active gear on the other.

14 gauge steel to ASTM A569, finished in Telco gray powder coat. That is the standard telecom frame spec, and the gray powder coat matches existing telco bay lineups rather than a black data center finish.

No. It is an open frame rack, a bare steel bay with mounting rails, not an enclosure. If you need locked access or airflow containment you want a cabinet instead. Open bays are chosen for cable access and heat rejection in telco and MDF rooms.

Top angle refers to the angle member across the top of the frame, which is the mounting point for overhead cable runway and auxiliary framing channel. If you are tying the bay into a ladder rack system above, that top angle is what you land the runway on.
