We had the Ultra Glide door closure & latching system installed on our sliding glass door yesterday. We're very happy with the quality of materials used, the smart design, price & even more impressed by the company itself. The system in full, is kinda involved for the average joe to install themselves, but the fact that they're willing to waive the installation fee ($50) & let you install it yourself is pretty cool! But honestly, it's So worth it to get the warranty & save yourself the headache. Gary S is dead on- they're honest & knowledgeable.
We tried Slide Right first & the installer Eric actually lifted the front wheels on our door (so it would slide poorly) & told us they would need to charge $100 more to "repair" our door for their system to work. Door Closing Systems threw in a part that would help control the high speed closing of our door. I'm SO impressed!
