Yes. The SB5842140TG is built as a Seismic Zone 4 network bay open duct rack, so it is the version to specify where the structural drawings call for Zone 4 anchorage. It is also UL Listed. Anchorage to the slab still has to follow the engineer's detail, but the frame itself is the Zone 4 build rather than a standard commercial rack.

The mounting rails are tapped 12-24, so standard 12-24 rack screws go straight in with no cage nuts. If your patch panels and switch brackets were pulled off a square-hole cabinet using M6 cage nuts, you'll need 12-24 hardware instead.

66 mounting spaces of usable rail. On a 140 inch tall frame that is a full-height telco bay, so plan on overhead ladder rack clearance and ceiling height before committing. If your room has a dropped ceiling or low soffit, a shorter 45 space rack is the safer buy.

Yes, the frame is a 19 inch width, which is the standard EIA rackmount opening, so 19 inch patch panels, switches, and UPS shelves mount directly to the 12-24 rails.

It's an open frame rack, not a cabinet. There are no doors, no side panels, and no locking front, so equipment and cabling are fully exposed on all sides. That's what makes it easy to cable and cool, and it's why it's normally used in a secured telecom room rather than an open office or public corridor. If the equipment needs to be locked away, an enclosed cabinet is the right product instead.

Top angle style means the frame is finished at the top with an angle rather than a channel or a plain flat cap, giving you a surface at the top of the bay to tie overhead cable runway or ladder rack into. On a 140 inch bay that overhead connection is usually how the rack is braced back to the structure in addition to the floor anchors.

The rack weighs 108.94 lb. At that weight combined with a 140 inch height, it's a two-person set and stand, and it has to be anchored to the floor before any equipment is loaded. Don't treat a full-height bay as freestanding at any point in the install.

Order model SB5842140TG. That single part number covers the Zone 4 open duct network bay in Telco gray with 12-24 tapped rails and 66 mounting spaces, so there is no separate finish or hole-pattern option to specify.

Steel to ASTM A1011SS, finished in Telco gray powder coat. That's the standard telecom gray, so it matches existing B-Line bays and most central office ironwork already in a room. Powder coat over steel holds up in unconditioned MDF and IDF spaces better than painted sheet.
