Clopay EZ-SET Torsion Springs

the idler seems to work fine. I did a changeover from old chain to belt.

GENIE 3850R works very well with my GENIE receiver #315390R2 that I have operating an old Chamberlin opener. The receiver was not included in the installation instructions but they were the same as the first (A) instructions you sent. You probably know all this but just in case not I thought I would comment anyway. Thanks

Happy with both torsion springs. Door is working as expected.

Thank God I found this website this was a Sears garage door opener and they stop making parts for it but they had it saved me over $200 to get a new one.Got the part fast perfect fit thank you guys once again.

very prompt; I will not hesitate to order something I need in a hurry if I cannot find it here in the Detroit area. Thanks
