I received four new puleys from Preferred Doors and installed them on my old 1972 vintage garage door today. It now opens and closes very smoothly and quietly, just like new again!
I couldn't find a local door company that would sell me springs without the installation service, so I looked on the internet. Preferred Doors had what I needed at a very competitive price. Their customer service was very responsive, and I had my springs in less than a week. I installed them the next day, and my garage door is back to working as it should.
I ordered a Liftmaster Chamberlain Garage door opener comp gear kit. The part came as described. It was delivered promptly. Garage door opener is back working fine.
