UP/DOWN/STOP SWITCH

Push Button Convenience

Just push a button and our door will go up or down. Our doors are
powered with a heavy duty 1 H.P. motor. We use aircraft cables or lift
straps on our power winches to raise and lower the door. You may stop
the door at any desired height and the door will shut off automatically
when it reaches the top or bottom. All of out doors are fused for safety!

It's So Easy! It's So Simple!

The beauty of it all is that it takes the chore out of opening and closing
your doors. Sliding doors are usually half closed, dangling in the wind
and not very neat looking - but with an "Automatic Bi-Fold," it's so
simple! A push of a button and your door will be closed, it's no longer a
chore!
