B-Line Eaton auxiliary support accessories, Steel, Telco gray powder coat, Angle size 1-1/2" X 1-1/2" X 3/16", Support angle

It's a 1-1/2 inch by 1-1/2 inch angle with 3/16 inch thick legs, cut 5 inches long. So each leg gives you 1-1/2 inches of bearing surface, which is what determines whether it will sit on your existing flange or channel run.

No fasteners are part of the SB212C05TG. You're buying the steel angle itself, so plan on ordering the bolts, nuts, washers, or concrete and masonry anchors separately to suit the structure you're fastening to and the thickness of the member you're picking up.

Steel, with a Telco gray powder coat. That gray is the standard color for telecom and data center cable runway and ladder rack, so it blends with existing B-Line runway rather than standing out as a mismatched piece.

Powder coated steel is meant for dry indoor use, which is where Telco gray runway and support hardware lives. For damp, corrosive, or exterior runs you want hot dip galvanized or stainless support hardware instead, not a powder coat over bare steel.

It's a short auxiliary bracket, an L-shaped steel clip used to pick up and support cable runway, ladder rack, or channel where the main run needs an extra bearing point, a wall or ceiling tie-off, or a transition between members. At 5 inches long it is a bracket, not a spanning member, so it carries load close to the structure rather than bridging an open gap.

Ordering is by the single model, SB212C05TG, with one configuration only, so there are no size, length, or finish choices to specify. If you're supporting a runway at several points, order the quantity of angles you need for each bearing location.

The SB212C05TG is a plain structural bracket and no certification applies to it. Where your inspector wants a listing, that requirement normally lands on the runway, raceway, or grounding components in the run rather than on an auxiliary steel support clip.
