B-Line SB556084XUTG Eaton series open frame racks, Self squaring with tapped assembly holes, Double sided, Aluminum, Telco gray powder coat, Telco style, Self-supporting aluminum relay rack, 11 gauge, ASTM A570

The SB556084XUTG is a 19 inch rack, 84 inches tall, which is the full-height Telco style open frame used in comms and equipment rooms. Width is listed at 19 in and height at 84 in, so it accepts standard 19 inch rack-mount gear and stands seven feet once floor-mounted.

No. The SB556084XUTG is a self-squaring frame with tapped assembly holes, so the uprights and base square up during assembly without a separate squaring kit. It is also self-supporting, meaning it stands on its own two uprights rather than needing a wall or cabinet to carry it. You still anchor it to the floor and, per your local practice, bond and brace it.

Yes, the SB556084XUTG carries a UL Listing. For institutional and government specs that call for listed equipment support in a communications room, that is the line item the inspector looks for.

Double sided on the SB556084XUTG means both the front and rear faces of the uprights are punched and usable, so you can mount gear from either side of the frame. That matters in a room where you feed cable from the back or want patch panels facing one aisle and active equipment the other.

Aluminum, built from 11 gauge material to ASTM A570, and the frame weighs 33 lb. That is light enough for one person to carry up a stairwell or into a tight closet, which is the usual reason an aluminum relay rack gets specified over a steel one.

An open frame like the SB556084XUTG gives you access from both sides and unrestricted airflow, and it is the cheaper, lighter way to hang patch panels, blocks, and switches in a secured room. Pick an enclosed cabinet instead when the space is shared or public and you need to lock the gear away, or when you need doors for airflow containment. The open frame offers no physical security by itself.

Telco gray powder coat, which is the standard finish on Telco style relay racks and the one most existing rows in a central office or MDF are already wearing. If you are extending a line of gray Telco frames, the SB556084XUTG matches visually.

Plan the footprint off a 19 in width and a listed length/depth of 84 in for the shipped assembly, with the erected frame standing 84 in tall. Add working aisle on both faces since the rack is double sided and gear mounts front and rear.
