The 26 gauge corrugated door curtain is manufactured from full hard galvanized grade 80 steel and coated with siliconized polyester pain that is back by a 25 year film integrity and a no-fade limited paint warranty. Available in sizes up to 12’0 x 18’0 and in over 20 different colors.
Tough, durable, wide, heavy duty nylon striping that controls curtain stretch and works in conjunction with the vinyl guide strip to reduce wear and deadens sound.
|The slide bolt lock assembly affixed to the bottom bar at each end of the door curtain gfastens through the guide to securely keep the door locked and in the down position. Padlocks can be attached to the slide to further secure the door.|
|The door stops make installation quicker as they can be installed by pivoting them through the punched location in the door brackets.|
|12″ diameter drums allows for lower headroom requirements. an enclosed barrel houses the dead axle assembly and protects the factory lubricated springs from direct contact with environmental elements. The inherent strength provided by the spiral barrel minimized axle deflection providing smoother operation. Because the curtain is attached by screws and not seamed to the barrel, cost effective replacement of either independent assembly is quick and easy.|
|Grease-filled, shielded radial ball bearings at the drums provide longevity and smooth operation. Factory installed insert nuts help make the installation of the chain hoist and operator sprocket easier.|
|A cam-action spring tension holding device allows quick, easy and equal adjustment of the tension on all springs simultaneously from one end of the door. The cam tensioner bites into the axle helpong to eliminate the unwanted spinning of the axle during the initial spring loading or adjustment process.|
|A reduced drive chain hoist for smoother operation on doors over 10’0″ wide or 10’0″ tall.|
|Mounting brackets are engineered and designed with deep embossing for strength and independently tested to withstand more than 2,700 pounds per pair. The installation friendly mounting brackets feature safe rounded edges and slots that allow for easy vertical adjustments as well as various installation preferences.|
|Convenient spring tension adjustment is accommodated by inserting a common 1/2″ ratchet tool into the end of the drive shaft and rotating. Initial loading of the door tension can be easily accomplished with a ratchet without the difficulty of spinning the door. This innovation also allows the tension to be easiliy measured and managed with a torque wrench.|
|Vision panel provide outside visibility and allow light entry through the 5″ x 17″ panel. Constructed of a translucent polycarbonate panel inside a glossy white 20 gauge frame, the panels create no interference with the operation of the door. The location and number of vision panels limited by door size. Ask a sales representative for details.|
|The electrical operation kit includes a sprocket and torque struts that equip the door for wall mounted jackshaft electric operators and can be furnished in lieu of reduced drive chain hoist when provided.|
|Gliderol electric operators are internally enclosed in the barrel to provide quiet and reliable operaiton. The operator’s design is compatible with transmitter and receivers, pneumatic sensing edges and otherelectric operation accessories. The operator side must be specified when ordering. Ask a sales representative for details.
Header seal attaches directly to the header and extends up to 5″ to the door curtain to form an effective barrier from environmental elements.
Top draft stop mounted to the door curtain provides a 2-1/4″ weather seal between the door and the header.
|Insulation is made of a foil backed, dual layer of heavy-duty polyethylene air-bubble insulation secured in place with a strong adhesive and joined by mylar film to provide an R value of 4. (Top draft stop and side draft stops are also included.)|
