发明名称 EZ2 seal door
摘要 EZ2 Seal Door is a device that secures to a doorway or other opening to prevent dust or other debris from circulating from one room to another during a construction or renovation project. A kelder welt is sewn into the outer edges of a canvas door. The welt is threaded through an aluminum or plastic track and this track is then mounted to the opening of the door providing a tight seal. The canvas door has a dual double pull zipper located in the center of the door that provides access to and from a sealed area. A small window is sewn into the canvas door to allow easy viewing into the sealed area.
