Janus 3652 Brochure

Model 3652 Rolling Steel Door

The Janus series 3652 is our certified wind load rated rolling sheet door that meets the specified wind loads required by even the most stringent building codes.  Independent laboratory testing proves how durable and strong this door really is.  The quick installation and smooth operation further demonstrates how user friendly this door is.  Backed by a one year warranty, this door is built to perform.

Color Chart
The 26 gauge corrugated door curtain is manufactured from full hard galvanized grade 80 steel and coated with Super Durable polyester paint that is backed by a 40 year film integrity and 25 year no-fade limited paint warranty. Independently tested in accordance ASTM E 330 and ANSI/DASMA 108, the series 3652 meets requirements of the International Building Code and Florida Building Code (FL14425).  Design wind load is rated +36 PSF and -40 PSF for opening width of 12'0".  Ratings vary for other opening widths, so please consult us for those widths. Available in sizes up to 18’0” x 20’0” and in over 20 different standard colors.

Guide Strip

 Tough, durable, wide, heavy duty nylon stripping helps control curtain stretch while deadening sound and reducing wear.  The nylon wind-locks provide strength to meet the stringent wind load requirements when engaged under load; however, easy operation is provided during load-free operation because the wind-locks do not come in contact with the guide.

Slide Bolt

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.

Door Stop

The flat door stop slide makes installation quicker. Simply slide through the holder on the guide and affix with a fastener.

12" diameter drum

12” diameter drums allow 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 minimizes axle deflection providi
ng 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.

Radial Ball Bearings

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.

Cam Action Spring

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.

Reduced drive chain hoist

A reduced drive chain hoist allows for smoother operation on doors over 10’0” wide or 10’0” tall.

Mounting Brackets

Mounting Brackets are engineered and designed with deep embossing for 

strength, and are 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.

Spring tension adjustment

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 easily measured and managed with a torque wrench.

Electrical operation sprocket kit

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.

Pantheon electric operator

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 hand side must be specified when ordering. Ask a sales representative for more details.


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.)


The header seal attaches directly to the header and extends up to 5” to the door curtain to form an effective barrier from environmental elements.

The top draft stop mounted to the door curtain provides a 2-.” weather seal between the door and the header.

Universal mount 2 1/2” deep 16 gauge galvanized steel guides require no pre-installation modifications for wood, steel, concrete or masonry block applications.
