B-Line Eaton series open racks, Double sided, Steel, Telco gray powder coat, 12-24 panel mounting holes, 45 mounting spaces, Top angle style, Seismic

The Eaton B-Line SB5868084UTG is built as a Seismic Zone 4 network bay closed duct rack, so it is the version to specify when the drawing calls for seismic anchorage in a Zone 4 location. Frame steel is ASTM A570 grade 33, and the rack is UL Listed.

45 mounting spaces on an 84 inch tall frame. That is a full-height open bay, so plan your panel and switch layout against 45 usable spaces rather than the 42 you get on a shorter cabinet.

The mounting rails are punched with 12-24 panel mounting holes, which are tapped threads. Your patch panels, rack-mount switches and shelves attach with 12-24 screws directly, no cage nuts or square-hole hardware needed. If your gear ships with 10-32 or M6 screws, order 12-24 hardware to match.

Footprint and envelope figures given are 84 in height, 84 in length/depth and 23 in width. Frame weight is 122.85 lb bare, before equipment, so size your anchors and your slab loading on the loaded weight, not this number.

Double sided refers to the closed duct configuration being usable from both sides of the bay, which is how network bays get ganged in a row with cable duct running through. It is an open frame rack, not an enclosed cabinet, so there are no side panels or doors to secure equipment behind.

An open frame bay like the SB5868084UTG gives you the cheapest access and the best passive airflow, and it is what most telecom rooms and MDFs use for patch panels, cross-connect and switches. Go to an enclosed cabinet instead when you need physical security on the equipment, dust control, or a locked door for audit or tenant separation. Open racks put no barrier between the gear and anyone in the room.

Top angle construction means the frame is finished with an angle across the top, which is the mounting surface for overhead ladder rack or cable runway landing on the bay. If your design runs cable tray above the rows, this is the style you want rather than a plain flat-top frame.

Telco gray powder coat over steel, which is the standard color for telecom bays and will line up with existing B-Line gray racks in the same room. Powder coat over ASTM A570 grade 33 steel holds up to handling during install better than a painted finish.

One configuration only: model SB5868084UTG, 84 inches tall with 45 mounting spaces, double sided, Telco gray. There are no height or finish choices to specify on this one.
