2.25 Inch ID Torsion Springs

Just follow a direction on the assemble manual and everything works as expected.

No problems. Pulleys came very fast. Price seemed good, and so was the quality. Would definitely use this website in the future.

My son bought a home that had a worn out garage door opener but your parts were the perfect replacement to get things working again. You tube has some great videos on how to install the gear and sproket assembly. Between that and your quality parts he should be set for years to come.

Easy ordering process! Received in a timely manner! Perfect fit! Very reasonable price! Will order from Preferred Doors for future needs, and will recommend Preferred Doors to others!!

Got the hinges on time and a great price fit perfectly wife happy
