Yes. The SB5842090TG open frame rack is built as a Seismic Zone 4 network bay open duct rack, and the frame is 6 gauge steel. It is UL Listed. Anchoring to the slab and any overhead bracing still has to follow your engineer's detail, but the rack itself is the Zone 4 version of the B-Line series rather than a standard-duty frame.

41 mounting spaces on a 90 inch tall frame. That is the usable panel height for switches, patch panels and rack-mount gear. If your equipment list totals more than 41 RU you need a second bay, not a taller version of this one.

Yes. The frame is 19 inches wide, which is the standard EIA rack width, so 19 inch switches, patch panels and shelves mount straight to the rails. The rails are drilled 12-24 tapped panel mounting holes, so no cage nuts are involved, just 12-24 screws.

12-24. The SB5842090TG rails are tapped with 12-24 panel mounting holes, so order 12-24 rack screws and washers. 10-32 hardware will not thread into these rails, and that is the most common mistake on a telco-style rack since network gear ships with mixed screw kits.

No. The SB5842090TG is the bare open frame only, a steel two-post network bay with 12-24 tapped rails and a top angle. Vertical cable managers, horizontal managers, rack shelves, ladder rack, grounding busbar and mounting screws are all separate items. Budget those into the job so the bay does not arrive with nothing to dress cable into.

An open duct rack is a two-post frame with no doors or side panels, so cable comes in from overhead ladder rack or duct and drops straight onto the rails. The top angle style on the SB5842090TG gives you a flat angle across the top of the frame for attaching runway, ladder rack or overhead duct. Use an open rack where cabling density and access matter and the room is already secured. Use an enclosed cabinet where you need physical security, dust control or forced-air containment, since an open frame gives you none of those.

Work to 19 inches wide with a 90 inch length/depth dimension on the frame itself, plus service clearance front and rear. Since this is an open two-post bay with no doors, you do not need door swing clearance, but you do need working room behind it for patch and power, and overhead space for the duct or ladder rack that lands on the top angle.

Yes, the rack carries a UL Listed marking. That covers the submittal line item many institutional and government specs include for equipment racks. The part number to put on the submittal is SB5842090TG from Eaton B-Line.

82.46 lb bare, as a 6 gauge steel frame 90 inches tall. It is a two-person lift and stand purely because of the length, not the weight. Plan your floor anchors before standing it up; the empty weight is nothing compared to the loaded weight once gear is in the 41 spaces.

The SB5842090TG is finished in Telco gray powder coat over steel, which is the standard gray used across the B-Line open frame line, so it lines up with existing telco bays rather than standing out as a black cabinet would. If your room is standardized on black, this frame will not match it.
