ABSTRACT:
The invention provides a roll-up door for operation with a pre-tensioned balancer and having fastening apparatus comprising a cable with fasteners, one on each end, and which is coupled to the door at first and second positions spaced substantially equally from respective sides of the door. The balancer has a clip located centrally with respect to the first and second positions so that as the cable is positioned on the balancer during initial installation, the cable can adjust in the clip so that the lengths of the cable from the balancer to the door are equalized. The cable is wound onto the balancer as the door is opened. This winding creates sufficient friction between the cables and the balancer to lock the cables to the balancer so that the cables effectively retain their equal lengths during use.
