This kit made installing the springs easy. I bought a few parts at the hardware store because the person who attached the previous springs had rigged up something a bit non-traditional. I wanted the install to be easy, so I used what was already in place and replaced what was necessary (springs and pulleys).. I might buy another set just to have as back-up...
The door control worked perfectly with my new +2.0 security Chamberlain door opener. It was easy to install, inexpensive and well made. The customer service was outstanding.
