Track Brackets are used to create a pipe track, most commonly used in sliding gate, or rolling gate, chain link gate systems. Each bracket includes an adjustable U-bolt (3/8" diameter) that wraps around the outside of a fence post and is then fastened secure. Once mounted in place, a piece of 1 5/8" outside diameter pipe or tubing (round) is slid over the male member of the bracket. Note, there are two male members per bracket, this is because the pipe track can run in either direction or both.
