Janus Series 650

The Janus Model 650 Mini Storage Door is designed and manufactured with durability, quick installation and ease of maintenance in mind.  Features standard to this door eliminate the need for extra options or upgrades.  The best door and the best value.  That's the Janus Advantage.


Door Springs

Door Springs

During production, each spring is coated with a generous amount of grease that penetrates the innermost 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 a smoother door operation. Finally, the spring and axle assembly is enclosed in a tube to protect them from the elements encountered throughout the life of the door.

Optional Package Protection & Shipping

Optional Package Protection

Doors stacked on top of each other in transit are going to shift... unless they can be packaged in a way to minimize the sliding that occurs during that time. Janus has found the way. As an option, we can suspend each door individually in crates. Whether they travel down the block or across the country, compaction damages, 
door abrasions and chatter marks are virtually eliminated. 

 Ratchet Tensioning Device

Ratchet Tensioning Device

The Janus 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.

 Radial Ball Bearings

Radial Ball Bearings

Janus supplies radial ball bearings at no additional cost to you. Our permanently- lubricated bearings require no maintenance and are guaranteed to last the entire life span of the door. 

 Dead Axle & Torque Tube Assembly

Dead Axle and Torque Tube

This design, noted for its durability and smoother operation with commercial applications, has now been incorporated into the Janus 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. The greatest feature of this design is that it affords the fine tuning of any spring adjustment to equally affect all springs on the door at the same time. 

 Door Stops

Door Stops

Our removable door stops are simple to install and prevent the curtain from over traveling the guide when raising the door

 Magnetic Zinc Coated Steel or Optional Stainless Steel Latch

Door 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 guide- mounted security devices. This versatile design affords you the ability to utilize padlocks, cylinder locks or both.

 Door Curtain

Door Curtain

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. Available in sizes 
up to 10’0” x 10’0” and in over 20 different standard colors.  Click here to view the color chart.
