Wayne Dalton Torquemaster Spring - Torquemaster Plus / 7 ft high/Between 70-79lbs - Single Spring

The spring was fine. I had a 73 pound door, 7 feet high, fit the spring specs perfectly. However, I ordered the Torquemaster Plus (plastic, hexagonal winding end) instead of the Torguemaster One (steel, rounded winding end). They connect to different winding mechanisms. Fortunately, I was able to remove the steel end from the broken spring and switch it with the plastic end on the new spring. Everything is working fine. The difference between the winding ends is clearly explained in the Torquemaster One advertisment, but not the Torquemaster Plus advertisement.

Factory fit,if you have a late model leave the plastic sleeve out.

Replacing the old one that was broken
