B-Line Eaton series open racks, Self squaring with tapped assembly holes, Double sided, Aluminum, Flat black powder coat, Top angle style, Seismic Zo

The SB556096XUFB is built as a Seismic Zone 4 rack, which is the highest of the legacy seismic zones and covers the areas most local codes treat as highest risk. It is also UL Listed. Anchoring and any required bracing per your structural drawings are still the installer's responsibility, but the frame itself is the Seismic Zone 4 version rather than a standard duty frame.

Double sided means the frame has mounting on both the front and rear faces, so you can hang equipment or panels from either side rather than front only. Plan the room layout for access to both faces, since an open frame rack has no doors or side panels to work around.

No. The SB556096XUFB is a self squaring design with tapped assembly holes, so the frame pulls into square as you tighten the assembly hardware. That saves the measuring and shimming you get with bolt-together frames that rely on clearance holes.

The assembly holes on this B-Line rack are tapped, so no cage nuts or clip nuts are needed for frame assembly. Order machine screws to match your equipment rails.

The uprights are a closed duct profile with unequal flanges, which gives an enclosed channel along the vertical for routing cable inside the rack member instead of strapping it to the outside of the frame. The unequal flange means one leg is wider than the other, giving a deeper mounting face on the equipment side. Material is 11 gauge to ASTM A570.

Top angle style means the frame carries an angle member across the top of the uprights, which is the tie point for overhead cable runway or ladder rack. If you are supporting the rack off the ceiling structure or bringing cable in overhead, this is the version you want; a rack without the top angle needs a separate bracket kit for that connection.

An open frame is the right call in a secured, dedicated equipment or telecom room: full access to all four sides, easiest cable management, and lowest weight, 36 lb here. Go to an enclosed cabinet instead when the gear sits in a shared or public space and needs locked doors, or when you need dust and airflow containment. The SB556096XUFB has no doors or side panels.

Flat black powder coat. Powder coat holds up in conditioned equipment and telecom rooms without the touch-up a painted frame needs, and flat black keeps the frame visually recessed behind mounted gear. Only the one finish is offered on this model.

36 lb. That is a one or two man carry for a 96 inch frame, which is what you get with aluminum rather than steel uprights. Set it in position and anchor it before loading equipment.
