A solid, stand-alone door can be built into the zippered doors of our closing fabrics in certain positions: when the closing fabric is in the back and into the closing fabrics of all mid-panels. The double door with a stable aluminum frame and shatterproof glass is also equipped with push bars. Alternatively, a tent fabric can be hung in the aluminum vertical frame. The zippered doors of the closing fabric (built into every closing panel and therefore not an extra accessory) can be rolled up or gathered and create a convenient entrance.
