DOOR SPRINGS During production, each spring is coated with a generous amount of grease that penetrates the pores of the spring with additives, displacing moisture and preventing the formation of rust and corrosion. In addition, this process relieves the friction created between spring coils thereby providing smoother door operation. Finally, the spring and axle assembly is enclosed in a tube to protect from the elements encountered throughout the life of the door

RATCHET TENSIONING DEVICE The ratchet tensioning device supplied as standard equipment on our door offers a simpler method of tensioning while more accurately fine tuning all the springs on the door at the same time. There is no extra hardware required. Eight different positions on the tension wheel allow one to perfectly balance the door every time. There are no pins required to hold the tension on the spring. You simply just click it.

DEAD AXLE & TORQUE TUBE ASSEMBLY This design, noted for its durability and smoother operation with commercial applications, has now been incorporated into the self storage door. The tube housing protects the springs and strengthens the axle. Eliminating axle push and shift that can occur with a live axle, the dead axle design allows for a straighter travel path of the door curtain in the guides.
