A fairing saver is a device to protect aerodynamic fairings on a semi-truck from damage while it is being towed backwards. The device utilizes two (2) pairs of clamp style locking pliers. However, in lieu of conventional jaws, each jaw surface on the present Fairing Saver consists of a hard plastic pad, each measuring three inches (3″) by six inches (6″). These pads are backed by a steel plate which also provides a pivoting pin that attaches the pad to the pliers. These pliers are then attached to the fairing surfaces of the truck. An attachment clip, welded to each of the pliers, is then used with a ratchet strap or turnbuckle, to keep the sides of the fairing from moving about during the towing process. The locking plier nature of the device means that it can adapt to any thickness of fairing and locks in place with the ultimate in holding power.
