Past reviews I usually take with a "grain of salt" but these guys shipped so fast it was impressive. Everything was exactly as presented online. One of the quickest "fixes" I have had.
Ordered May 12, 2020 late in the day. Here at my house (Md) by noon Fri May 15. Great service from PDoors! Installed pulleys today. They have to be better than the junk ones sold in the big box stores. My door is old, 500lb. no longer made. As others have said the replacement pulleys don't make it a yr. Trying these. Will update as some time goes by...So far great..
I measured old spring and ordered a replacement from Preferred Doors. The spring took a few days to get due to supply chain delays these days. When it arrived, it was packed well, and it was what I ordered and expected. I installed it without any problems, and my door is working again. Time will tell how well it holds up, the old spring lasted over 10 years.
