How Many Turns of Spring is Recommended for M-3 Enclosed Trailer Ramp Spring # ERS120D81
Published 01/30/2019
Question:
How many turns of the spring is recommended for this when installing?
asked by: Clayton D
Expert Reply:
I checked with M-3 and when you are ready to wind the spring on the Enclosed Trailer Ramp Spring # ERS120D81 you will need to use two 1/2 inch diameter bars (of around 18 inches long). You will insert the first bar into the winding cone of the spring and pull down. The system is then designed for 10 full revolutions of the spring. It will be easier to balance the door if the spring is wound in quarter turns.
Please note that we highly recommend only installing this if you have had previous experience winding torsion springs. Otherwise you will want to have a certified professional (like a local garage door company) perform the install.
I have included a short video review on this ramp spring that you can check out as well.
