Standard Features:
• Sealed Ball Bearings: Self-aligning and allow lasting free rotation.
• Drum Assembly: The counter balancing mechanism is housed in this unique, roll-up assembly.
• Maximum Security: All slats are manufactured from the highest quality galvanized steel with a baked enamel finish, to form an effective secure curtain. Two slide bolt locks standard on all doors. (Available in 24 or 22 gauge.)
• Weather Seal: A blade astragal made from E.P.D.M., a highly resilient and flexible rubber compound, runs the full length of the bottom angle to seal the threshold of the opening. This forms a barrier against weather, dirt, insects and rodents.
• Guides: Two pieces roll formed steel guides standard on all standard doors. Windlocks provided on larger sizes.
• Chain Operation: A minimum of a 4 to 1 reduction standard on all doors. Smooth hand-chain provides safe and comfortable operation eliminating the sharp edges common to lock link hand chain.
• Slat Configuration: All doors available in curved or flat slats. Galvanized according to ASTM A653-G60 and finished with baked epoxy primer and baked polyester topcoat.
• The Porvene Secret: State of the Art technology has allowed Porvene Doors to create a Door Dynamometer which accurately measures the torque characteristics of roll-up doors.
