B-Line Eaton series open racks, Aluminum uprights and steel extension brackets, #12-24 panel mounting holes, Flat black powder coat, Double sided uni

Yes. The Eaton B-Line SB704233930FB is a 19 inch panel mount open frame rack, so any standard 19 inch EIA rack-mount switch, patch panel, or shelf bolts straight to the uprights. Mounting holes are tapped #12-24, so you use #12-24 rack screws rather than 10-32 or metric M6.

Plan for a footprint 39.25 inches high by 39.25 inches wide, projecting 30 inches off the wall. That 30 inch depth is the number that catches people out in a small IDF closet or above a door, since you still need working room in front of it for cable dress and to pull gear. The frame itself weighs 18.7 lb before any equipment goes in, so wall fasteners need to be sized for the loaded weight, not the frame.

Double sided universal means both front and rear upright pairs carry mounting holes, so you can mount equipment from the front and back of the frame instead of a single mounting plane. That is what lets you hang patch panels on one side and switches on the other, which is the usual way these get loaded in a wall-mounted closet.

A wall-mounted open frame like the B-Line SB704233930FB gets the gear off the floor and is the right call when floor space is tight and the equipment load is modest, but it depends entirely on having structure in the wall to carry it. It projects 30 inches from the wall and stands 39.25 inches tall, so it suits a patch field plus a few switches. If you are loading deep servers, UPS units, or a full 45U of gear, go floor-standing instead, since a wall mount transfers all of that into the wall framing.

What you are ordering is the open frame itself, aluminum uprights with steel extension brackets. Wall fasteners are selected to suit the wall you are mounting into, whether that is wood studs, steel studs, or concrete, so plan on supplying those separately along with your #12-24 rack screws for the equipment.

Order Eaton B-Line part number SB704233930FB. That is the flat black powder coat, double sided universal open frame with aluminum uprights, steel extension brackets, and #12-24 panel mounting holes. There is one configuration, so no finish or hole-pattern suffix to specify.

It is a mix: aluminum uprights with steel extension brackets, finished in flat black powder coat. Aluminum uprights keep the frame light at 18.7 lb while the steel brackets carry the wall-mount load. Powder coat is a durable finish for a mechanical or telecom room, though this is an open frame with no enclosure, so equipment is exposed to dust and anything else in the space.

The Certifications entry for the SB704233930FB reads Not Applicable. It is a mechanical open frame, not an electrical device, so there is no listing attached to it. If your project spec calls for a listed enclosure or a bonded and grounded rack assembly, that is a different product family.
