The Extruded Composite Tough-Track is your cost effective track mounting solution. This version of the Tough-Track does not use end caps and features a tapered end allowing for stress-free insertion and removal of track accessories. The hardware sits in a sunken channel so the T-Bolt won't get stuck when sliding across the track. With pre-drilled holes for #8 screws, installing the Tough-Track is easy. Hardware not included. Dimensions: Overall length: 6" Overall width: .91" Track thickness: .52"
