Very pleased with my doors which I fitted myself. The on-line measuring guides are good, delivery came on the day specified and installation was straightforward. The majority of the install can be undertaken by one person but I did need the assistance of a neighbour for 20 minutes or so to unroll the door over the motor bar and guide into the side channels. The remotes were pre-programmed and worked immediately. My only difficulty was setting the up and down stop postions until it dawned on me that I ordered my doors with power to the left whereas the instructions relate to power on the right. It is the same motor bar, simply reversed, so the adjusters are reversed.
