B-Line Eaton auxiliary support channel, Steel, Pre-assembled channel, spacer, and hardware included, 5" length, Telco gray powder coat, 2" X 9/16" Sup

Nothing extra to order for the assembly itself. The B-Line SB220205TG ships pre-assembled with the channel, spacer, and hardware included. What you supply is whatever anchors the assembly to your wall, rack, or structure.

Steel with a Telco gray powder coat, which is the standard finish for central office and telecom equipment framing, so it matches typical rack and ladder rack hardware in those rooms. The powder coat is a painted finish, not galvanizing, so keep it to dry indoor use.

That's exactly what an auxiliary support channel does. The SB220205TG is a short 5 inch channel section supplied with a spacer, so it mounts the 2 inch channel face off the mounting surface rather than flat against it. For long continuous runs of framing you'd use full-length strut instead; this is a short auxiliary bracket for a single support point.

No listing applies to this item, and it isn't submitted as a certified component. It's a mechanical support accessory, so treat it as part of the framing and support system rather than a listed electrical device on your submittal.

Listed at 10 lb. That's a one-hand part for a single installer, but the mass sitting on a cantilevered 5 inch channel is worth accounting for when you pick anchors for the mounting surface.
