B-Line Eaton auxiliary support channel, Steel, Pre-assembled channel, spacer, and hardware, 3" length, Telco gray powder coat, 2" X 9/16" Support chan

The SB220203TG is a 3 inch long piece of 2 inch x 9/16 inch support channel. Catalog spec values back that up: 3 in length/depth, 2 in width, and .56 in height (9/16 inch expressed as a decimal). It is a short stub of channel, not a full strut length, so plan it as a spacer or standoff bracket rather than a run.

It ships pre-assembled with the channel, the spacer, and the hardware together, so you are not sourcing loose fasteners to put the assembly itself together. Anchors or fasteners into your structure or enclosure are a separate item, since those depend on what you are attaching to.

Telco gray powder coat over steel. That is the standard gray used on cable runway and rack hardware in central offices and equipment rooms, so it matches existing telecom framing rather than standing out. Powder coat on steel is an indoor/dry-location finish, not a galvanized or stainless option for wet or corrosive areas.

It is a short bracket that spaces a support off a wall, rack, or another channel so you can pick up a cable tray, runway, or conduit where the primary framing does not land. The SB220203TG version is 3 inches long with the spacer already fitted, so it sets a fixed offset between the mounting surface and whatever you are hanging. Contractors use these to clear an obstruction or to bring a run out to line without fabricating a bracket on site.

Order by manufacturer part number SB220203TG, from Eaton's B-Line series. That single number covers the 3 inch, 2 inch x 9/16 inch channel with spacer and hardware in telco gray, and there are no size or finish variations to specify under it.

6.5 lb per assembly. For a 3 inch piece that weight reflects the spacer and hardware included with it, and it is worth adding into dead load when you are stacking several of these along a runway, since the brackets themselves add up before any cable weight goes on.

No certification applies to this part. It is a plain steel support component, so ratings and listings are carried by the tray, runway, or raceway system it supports rather than by the bracket.
