1.75 Inch ID x 218

My original order came in short one item. Called about it, no problem they shipped it out right away. Very pleased with the customer service.

Ordered two remote openers. Easy to program. Up and running in lest than 15 minutes. It was all good they arrived in 3 day ready to go. Thank you.

The liftmaster repair kit was exactly what I needed. The parts arrived very quickly and the repair went well. I had enough in the kit that I could rebuild my old part so now I have a spare if ever needed. Thanks for the great service.

I have them on a 8 foot door. They stretch out to 71 inches with the door closed seem to work just fine. I do have a safety cable passing through the springs.

very prompt, excellent buying experience
