Had the part for an old sears opener that broke. Fit perfectly. Bought an extra one for next time. The one problem was waiting for USPS to deliver. Thanks for the quick response and would buy from again.
Opener works great, no louder than any other opener. Installation fairly easy, all the parts needed are in the box. Instructions are written in English.
I purchased 12 of the 13 Ball Nylon Garage Door Rollers that were very well priced. They appear to be good quality. It is the sealed type bearings. Only time will tell if the nylon will stand up to use I put them through. At the price I purchased them I got two extra just in case. They are already much quieter than the metal rollers. The older ones had been on their for at least 15 years and if these last that long, the next owner can replace them.
