TruXport Tonneau Covers work great in all climates. The industrial strength hook and loop system provides continuous contact between the rails and cover. It is easy to fasten even in freezing temperatures. The Pre-Set tension control is conveniently integrated within the latching system to keep the cover tight in any climate. Quick one person installation in 20 minutes or less with the easy no-drill clamps. No loose parts – the cover completely rolls up and self stores in seconds. Straight bows roll up with the cover and provide a smooth, flat look when closed.
