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.

The product was very good. Best I have seen in along time. My fault with the ordering was the size was too large for the trailer. Shipping time was very short. Just sorry the trailer was too small for the unit. 216730
