The 650 Series counter doors are constructed of high-quality interlocking flat slats for a tight fit that is both sleek and attractive. Endlocks secured to alternate slats maintain curtain alignment and prevent lateral slat movement. The counter balance assembly features heavy duty helical torsion springs in a steel tube or pipe barrel to provide long and reliable service. Optional crank or electric meter further simplifies door operation, and 24 month warranty — as well as our network of Overhead Door Distributors — ensures that your counter doors will perform like new for years to come.
