B-Line Eaton series open racks, Self squaring with tapped assembly holes, Double sided, Steel, Brushed aluminum finish, Telco style, Self-supporting

Yes. The SB556084AL relay rack is built to a 19 inch width, which is the standard EIA rack-mount panel width, so patch panels, switches and shelves with 19 inch ears will bolt straight to the uprights. It is a Telco style double sided open frame, so equipment can be mounted from either side rather than inside an enclosure.

No. The SB556084AL is a self-supporting aluminum relay rack, so it stands on its own base without wall bracing or top bracing to an overhead runway. You still anchor the base to the floor for a permanent install, and in seismic or high-traffic areas most specs will call for top bracing regardless of the rack's self-supporting design.

The uprights come with tapped assembly holes, so equipment screws thread directly into the rail. No cage nuts or clip nuts are needed for the rack holes. You will still need the mounting screws themselves and any equipment-specific hardware.

Yes, the SB556084AL open frame rack is UL Listed. That matters on institutional and government jobs where the drawing calls for listed support hardware in a telecom or equipment room, and it is the line a submittal reviewer looks for.

11 gauge steel to ASTM A570, finished in brushed aluminum. It is a steel frame with an aluminum-look finish rather than an extruded aluminum rack, which is worth knowing if your spec distinguishes between the two.

An open Telco style rack like the SB556084AL is the right call in a secured telecom or IDF room where you want both-side access for patching and cable dressing, and where airflow and cost matter more than physical security. If the equipment sits in a shared or public space, or the spec calls for locking doors and dust protection, you want an enclosed cabinet instead. This double sided open frame has no doors or side panels.
