Six Styles to Choose From

Quality - Our Top of the Line Door
Best Door Money can Buy
New patented "Lift Strap" System features durable polyester material. The number of straps depends on the size of the door. Adequately sized lifting drums give a 5:1 safety factor.
How Do The Straps Work
The straps wrap around the lift drums as the door opens. As the drum's circumference increases, the door opens faster. It's ideal! The door opens slowly, then picks up speed.
Why Consider The "New Lift Straps"
Already 90% of our doors get ordered with "THE NEW LIFT STRAPS SYSTEM" so it is obvious customers are catching on fast and for all the right reasons... It's a clean, strong design which makes it Faster, Safer, Simpler, Easier, Quieter, Smoother and most important it's been "Proven." Be sure to read our latest literature on the "New Lift Straps"
