Make opening truck curtains easier.

After decades using and repairing curtain tensioners, we wanted to create a new design that resolved common problems. Our Straitline Tensioner is the result: a tough, innovative tensioner that is easy to use, safer, and zero maintenance.

Designed by the Straitline team and launched in 2020, the Straitline Tensioner reduces the force needed to release curtain tension. The handle locks in the open position, leaving both hands free to open your side curtain. Make your life easier today!
