Ramp door spring is designed for enclosed trailers. The system features a dual drum and dual cable to prevent the ramp door from free falling in the event one cable is accidentally cut. The universal mounting bracket has two 3/8" holes that allow the installer to bolt the spring to the rear header. Welding the bracket is also an option.
Warning: The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system.
