Standard winch track, considered as C channel steel winch track, is designed for using with sliding winches. This winch track allows the sliding winch to slide effortlessly along the side of the trailer. HY ENVIROTECH offers three sizes in use: 3',6' and 12'. If you need to hold more sliding winches to tighten the cargo, then you can choose the longer winch track to provide you with more anchor points to secure the load.
