Replace your old trailer door spring with this heavy-duty, conventional ramp door spring. This dual-spring setup lets you easily open and close the ramp door on your enclosed trailer and eliminates the risk of your ramp door freefalling.

Meh
not strong enough at the start to strong at the end of cycle
Little more work then I thought it would be but when completed it worked excellent.
Works great. Door is still heavy to lift, but I can. Make sure you know how much your door weights and get a big enough lift. Thanks for the help.
Fast shipping
Box was damaged in shipping. Drum was off and heavy gouging on the ID of drum and on shaft. Holes in hardware bag and holes in the box. I don’t know if hardware is missing. There is not parts list or installation instructions. There was no foam or bubble wrap protector in the box
Good quality products with this company. Ordered 3/22/2020 and received 3/26/2020. Just what we ordered and works great. Would highly recommend this company to anyone. Thank you so much for your quick delivery.

After 1 year of use, it still works great.
Great turn around !
Great value was everything it said it was , easy to mount and adjust. It replaced the current assembly on a 1916 era house garage door
Great spring unit. I installed these springs to replace the lower hinge springs on my enclosed trailer ramp door. What a great improvement. This dual spring set was stronger than I needed so I removed one spring and keeping it for a back up. I wish I had done this years ago.

I see you are attempting to install this on an enclosed trailer ramp door. Unfortunately we do not have instructions on this but I will continue to look for instructions if this link does not help. There should be a single spring and dual spring install guide. I have a link below for your reference.
