      • Get the right unit first!

      This unit does not work with all Chamberlain chain drive units. I first bought an incompatible unit and did not discover the problem until I was well along in the assembly. Back to HD, bought the right unit for like eight bucks more and finished the install in an hour or two. Thank goodness for HDs generous return policy. All the parts fit perfectly, the instructions are clear and simple, and when your done it works like a charm. Lifts my eight by ten foot insulated steel double wall door with windows easily. Nice.
