Any upward-acting door may be fitted at the leading edge with an electro-mechanical safety weatherstrip.
This mechanism consists of a formed galvanized steel section covered with vinyl impregnated rubber hinged along the full width of the leading door edge.
Can be adjusted to approximately 2½" (63.5mm) to form a tight weather seal.
The hinge linkage is arranged that minimum pressure is required to activate the electrical control switch causing door to reverse direction of travel to the fully Open position.
Reverse switch is enclosed in a galvanized housing with a sliding plunger to assure positive actuation every time.
For doors up to 14 ft. wide one switch is required. Over 14 ft. two switches are required.
