Ramp Door Spring For 72 Inch Ramp Door

Question:

Hi! I am looking for a replacement torsion spring mechanism for a ramp door on a trailer. I am not sure how the measurements listed on the website are to be taken - can you point me at the correct part? I measured about 72 between the 2 spools on the existing mechanism. Lifting the door at the end comes in at 150 lbs. The existing mechanism has 1 spring and 2 brackets, no center bracket. Thanks

Sure thing, and for your 72 inch ramp door measured between the spools, what you need for a single spring and 150 lb weight capacity is the following:
