The liftslide door system from Weiland is a big, moving glass wall designed to operate effortlessly across spans as tall as 16-ft. or as wide as 60-ft. The European roller system lifts panels above a flush track, and when lowered, the weight of the door, the multi-point locking gear, and a special gasket system provide weather resistance and security. The flush bottom track projects only 3/16-in. above the finished floor, creating an almost seamless transition between spaces. For more information circle XXX on inquiry card.
