The Wall Mount Line Track Safety Bracket is made of durable galvanized steel and is used to mount a line track to a wall as part of a chain link fence system. It comes with pre-drilled holes to attach it to a wall or other flat surface. In most applications, one bracket is needed for each connection, typically every 8' to 10'. Most gates have top and bottom tracks, which would require one bracket each at the top and bottom of the gate. This safety bracket works exclusively with rails that measure 1 5/8".
