Extreme™ Series Sectional Door

High Performance Sectional

Model Number: EX3728

High Performance Sectional Door

When it comes to speed, our Extreme™ Series Sectional Door is in a class of its own. With speeds up to five times faster than a traditional sectional door, efficiency is at an all-time high.

Door components are also manufactured for the long haul. The springs offer double the life of that on a traditional sectional door along with heavy duty hardware, double end stiles and an upgraded lift cable for optimal performance. Roller life is also extended due to tandem nylon rollers, which also reduce running noise for a smooth and quite operation.

Designed with safety in mind, the Extreme Series Sectional Door comes standard with a light curtain that offers 3 feet of protection. It also includes a cable management system and standard cable monitor to prevent unwanted door movement. Wireless edge options are also available as an additional safety precaution.

The Extreme Series Sectional Door can be customized to fit your exact specifications. Model 904 offers a full-view vision window while Model 3200 and 3700 offers an insulated version to control temperature and noise transmission. This door can be customized to fit any needs of even the most unique application.

To round out this door, it is powered by a LiftMaster® operator. Featuring an average operating speed of 24” per second, the LiftMaster® operator has a direct drive system and lists daily duty cycles at 600 cycles/day over a two-year warranty period. This operator can also connect to wi-fi for seamless operation and has an easy-to-read display with easy limit-setting technology.

Applications: emergency service facilities, distribution in warehouses and automotive buildings.
