Features and Specifications:

• 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.
• The Series 850 Door was designed to meet stringent wind load requirements for mini warehouse applications while still providing the best door operation in the industry.
• 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
• Independently tested, the Model 850 meets the requirements of the Miami-Dade County Florida Product Control Division for high velocity hurricane zone (HVHZ) of the Florida building Code. Design wind load is rated +46 PSF and -54 PSF. Opening sizes up to 8’8″ x 10’0″ in white only.
• 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.
