The invention corrects three major safety and security problems, associated with millions of traditional sliding doors. It offers a dramatic, yet simplistic, solution to these chronic problems in addition to providing a smooth, maintenance-free operation. The invention eliminates the protruding longitudinal rails of the traditional floor track that create a barrier to foot and wheel traffic. In its place is a smooth, level track that conforms to the "Americans with Disabilities Act of 1990". Secondly, the invention is secure against unauthorized (forced) entry. Thirdly, the invention is not displaced by hurricane-force winds. For maximum strength and function, solid nylon rollers are positioned at each end between metal guides running the length of the panel base. Adjustable constraints are positioned at each end on top of each panel. The combination of the pair of guides seated into their respective track channels, and the constraints, prevent unauthorized entry and displacement. |
