B-Line SB5566096TG Eaton series open frame racks, Used to mount electronic switching equipment, Double sided, Steel, Telco gray powder coat, 12-24 panel mounting holes, Top angle style, Seismic Zone 4, open duct unequal flange rack, 11 gauge

Yes. The SB5566096TG is built as a Seismic Zone 4 open duct unequal flange rack, so it is intended for installations where seismic anchorage of equipment racks is required. It is also UL Listed. It is an 11 gauge steel frame, which is the heavier gauge used where seismic loading matters rather than light-duty relay rack stock.

The rails are tapped 12-24 panel mounting holes, which is the standard telco rack thread. Your equipment and panels mount with 12-24 machine screws; you do not use cage nuts or square-hole 10-32 hardware with this frame. If your gear shipped with 10-32 screws, order 12-24 hardware to match the rack.

The rack is listed at 96 in height, 23 in width, 96 in length/depth, and 101 lb. The 96 in height is a full-height telco frame, so check your ceiling clearance and cable ladder height before committing floor space. At 101 lb bare, plan on two people to stand it up and anchor it.

Double sided means the frame carries mounting rails on both faces, so equipment can be mounted front and rear rather than from one side only. That is typical for switching and distribution gear where you want access and mounting depth from both directions. It is an open frame, not an enclosure, so there are no doors or side panels.

An open frame rack like the SB5566096TG gives you all-around access, easier cable dressing, and free convection, which is why it is the standard choice for telco switching and distribution equipment in a controlled, access-restricted room. Go to an enclosed cabinet instead when you need physical security, dust control, or forced-air containment. This frame has no doors or panels, so anything needing lockable access should go in a cabinet.

No. The SB5566096TG is an open duct unequal flange rack, meaning the two flanges of the upright differ in width, which creates the open vertical duct for cable while still presenting a standard 12-24 tapped mounting face for your equipment. Panels and switching gear mount to that face normally; the cable side simply gives you more room to route.

Top angle refers to the angle member across the top of the frame, which is what you tie overhead cable runway or ladder rack to. If you are landing cable from above, that top angle is your attachment point, and you will need the appropriate runway-to-rack support hardware separately since it is not part of the frame itself.
