Marantec and ADS – Perfect Synergy in Garage
Door Opener Design and Installation


The garage door is the most used exterior door in a typical home, making a fully reliable and safe garage door opener a paramount question. Increasingly, knowledgeable consumers are looking at Marantec, masters of German engineering and makers of some of most sought-after garage door openers available to American homeowners. New construction and remodeling projects often specify wood, glass and double-strength insulated steel doors that are predictably heavier than light-gauge steel. This requires openers with greater horsepower and excellent longevity and reliability – while remaining quiet, safe and user-friendly.
