ZipWall Magnetic Dust Barrier Door Kit, MDK

Yes, it seems to be outrageously priced. And, yet, worth every penny! If you have a ZipWall "structure" that you need to get in and out of frequently, this is - to quote the old Western Airlines (RIP) catchphrase - "The only way to fly". Very well made and very well thought out - it simply works. High quality parts and first class engineering make it worth the cost. Like the video shows, you simply walk through it and it "snap" closes behind you effortlessly with out any fiddling or bad language. Should last for years. Hint - kick the bottom first as you walk through and it opens easily from the bottom up.

Super

Far superior to the zipper system that we have used many times before. A bit expensive but worth it in the end because it is reusable

works portable

This is a really nice door system but it does seem exceedingly expensive. I am a contractor and I regularly use Zip Wall for the remodels we do. I've found the Zip zipper wall to be virtually worthless as my guys are always breaking the zipper and it's a total pain to zip up and/or down for every entry and exit. While not perfect, this door provides a solid magnetic closure yet not so tight that the nylon doors tug too hard on the poles and dislodge the airtight seal.The zipper system seems to do a better job at establishing a nearly dust-proof enclosure but with the positive/negative draft that I establish with blowers, this wall works perfectly well. Instructions are almost not worth it. If you have reasonable mechanical ability, just set them aside and intuit how the door works - it's much faster.
