Mr Stefan: I am a garage door & opener wholesaler. Once I had complains & requirements from my customers which had made me upset- the noice from the rails; the dust in the chain rails; the longer time for installation; the requirement of bigger lifting force; the extra function like phote cells, battery back up; the short life time of the plastic gear motors and shafts, etc. When I am looking for someone to help me with the problems, I found MOC. MOC provides me with many professional solutions, and technical supports. Now I'm getting products with very good performance from MOC.
