Drive assisted roller assembly for rolling door

摘要: A coupling for a door/curtain includes plurality of mechanisms affixed to ends slats the door/curtain. Each mechanism roller mounting bracket having first arranged at an upper portion bracket, and extending portion, oriented approximately 90 degrees with respect bracket; least one second roller. is rotatable around axis perpendicular rotation The are so as cooperate outer track, inner support guide guides rail assembly ensure that moves rollingly within even when subjected deflecting force.
