Plan for a footprint based on 19 inches wide by 25.25 inches deep, with 84 inches of height for the frame itself. Add clearance above for the top angle and any overhead cable duct or ladder rack, plus working aisle front and rear since this is an open frame accessed from both sides.

The SB506084XUFB is built as a seismic zone 4 network bay closed duct rack, so it is the version to specify where a project drawing calls for seismic anchorage in zone 4. It is UL Listed. The rack still has to be floor anchored per the seismic detail on your drawings.

The frame is steel at 11 gauge to ASTM A1011SS, with a finished weight of 101 lb. That is the heavy-duty end of open frame construction, which is why it can carry a full 50 space bay of network gear and still meet the seismic zone 4 build. Anchor it to the slab before loading.

An open frame like this one gives you access from all four sides and the easiest cable management for patch-heavy MDF and IDF rooms, which is why it is the standard choice inside a locked telecom closet. Go to an enclosed cabinet instead when the gear sits in an unsecured area, a shared space, or a dirty environment where you need a lockable door and dust control. This one is open frame with a top angle for overhead duct and ladder rack attachment.

Finish is a flat black powder coat over steel, the standard black used across Eaton B-Line series open frame racks, so it lines up visually with existing black B-Line bays in the same room. If your installed racks are grey or clear aluminum, it will not match.
