B-Line Eaton series open racks, Steel, Flat black powder coat, 12-24 panel mounting holes, 65 mounting spaces, Top angle style, Seiemic zone 4, netwo

The rails are punched with 12-24 panel mounting holes, so you fasten equipment with 12-24 rack screws. No tapping or clip nuts needed, but note that gear shipped with 10-32 screws will need 12-24 hardware instead.

It is built as a seismic zone 4 network bay closed duct rack, the highest of the older seismic zone designations, and it is UL Listed. The frame is 6 gauge steel to ASTM A1011SS, which is what gives it the stiffness for that duty.

An open frame like the SB506096FB gives you all-sides access for cabling and passive cooling, and it is the usual choice for switch and patch panel bays in a secured closet. Go to an enclosed cabinet instead when you need locked physical security, dust control, or fan-forced cooling. This one is the open top angle style frame, not a lockable enclosure.

This is a floor-standing seismic rated frame, and for the zone 4 rating to mean anything it has to be anchored through the base to the slab, plus braced overhead where the design calls for it. Anchors and any overhead bracing kit are separate items, sized by your structural spec.

65 mounting spaces, which is 65U of usable panel height in a 96 inch tall frame. That is more than a typical 45U cabinet, so it suits a closet where you want maximum panel and switch capacity in one bay.

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 flat black bays in the same room.
