In cases where we are enclosed on all sides without a standard door. PES offers a roll up door. A roll up door is 36” wide section of a curtain that will have a zipper on each side to allow to entry and exit. This section will be unzipped and rolled by hand. It is kept up in place by 2 roll up straps that will keep that section raised to allow entry and exit. Also keep in mind the Roll up door can made custom to the width you want and can be placed anywhere within the width of the curtain itself. Once use of door is complete undo the straps zip the zippers down to secure.
