Trimaco’s E-Z Up Magnetic Door Kit helps create a quick, temporary dust containment enclosure. The pre-assembled kit includes one sheet of plastic with an attached magnetic dust door and one roll of release tape. Door Kit fits 3 x 7 ft entryways. The magnetic dust containment door creates a self-closing doorway, allowing hands free access. Carry tools, ladders and supplies in and out of the dust containment system without having to unzip and zip like other traditional door kits. Simply attach to a door frame and get to work. No need to waste time stopping and dropping your tools. In addition, the magnetic door has an open bottom for easy cart access.Reusable magnetic door kitHands-free access in and out of the jobsite
