The Model 3400 series commercial roll up door has been specifically engineered for Miami-Dade County, Florida. With an ability to withstand high winds, the sheet metal door meets Miami-Dade County’s stringent building codes. The door is also easy to install and uses a 12” drum wheel. Other features and specific measurements of the door are as follows:
- Maximum opening size of 12’ wide x 16’ high (192 sq.ft.)
- Push-up, hand chain and electric operations
- PSF Ratings: +43 PSF and -49 PSF
Features of the Roll Up Door Model 3400
Tough, durable and wide, heavy duty nylon strapping helps control curtain stretch while deadening sound and reducing wear. The 11 gauge windlocks provide the strength to meet the stringent wind load requirements when engaged under load; however, easy operation is provided during load-free operation because the windlocks do not come in contact with guide.
The slide bolt lock assembly affixed to the bottom bar at each end of the door curtain fastens 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 flat door stop slide makes installation quicker. Simply slide through the holder on the guide and affix with a fastener.
The 12” 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 minimizes axle deflection, providing smoother operation. Because the curtain is attached by screws and not seamed to the barrel, replacement of either independent assembly is cost-effective, 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 helping to eliminate the unwanted spinning of the axle during the initial spring loading or adjustment process
A reduced drive chain hoist for smoother operation is standard on all door sizes.
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.
Door Options For Model 3400
Magnetic Zinc Coated Steel or Optional Stainless Steel Latch – Our patented mini latch features a cover plate made from a heavy gauge yellow zinc coated steel or optional stainless steel. In addition, the latch cover protects the slide from tampering by completely covering the slide, with the exception of a tab used to operate the latch.
To further secure the door, the latch’s two-inch throw, with its magnetic properties, can be incorporated with the new guidemounted security devices. This versatile design affords you the ability to utilize padlocks, cylinder locks or both.
Top Draft Stop – 2 1/4″ Black “L” shaped neoprene weather stripping affixes directly to the door curtain where the curtain meets the header and provides a barrier to weather elements. Rolls up in the roll when the door is in the up position.
Hood – Recommended for exterior mount applications or for cosmetic look. If the door is being mounted on the outside of the building (where the drum is exposed to the weather elements) they’re going to want a hood (or protective over-hang) because the drum of the door isn’t weather-proof and will be damaged by rain, snow, etc. Insulated doors can’t be mounted on the outside of the building or have a reverse curtain.
Side Brush Seal – 2” Polypropylene Side Brush Seal with Aluminum Retainer mounts on the side your frame work. The flexibility of the brush allows complete seal of the roll up door corrugation. Keeping out dust, air flow, pesky insect and rodents.
Header Seal – The header seal is made to attach directly to the header of your door’s opening. Header Seal is gray in color and measures 6″ wide. This is an excellent way to block wind and debris from getting inside storage units or garages.
The Pantheon range of low voltage DC operators are designed to fit enclosed internally in the barrel of the rolling door, providing quiet and efficient operation but requiring only minimal side room. The logic controller is designed to be readily compatible with external transmitters, receivers, photo eyes and sensing edges. The operator is always fitted to the right side.
Insulation is made of a foil-backed, dual-layer polyethylene air-bubble insulation secured in place with a strong adhesive and joined by mylar film (top draft stop and side draft stops are also included).
Vision panels – This can 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 are limited by the door size. Ask a sales representative for details.
Universal mount 16 gauge galvanized steel guides require no pre-installation modifications for wood, steel, concrete or masonry block applications.
