Most dust doors are a hassle because they require the use of zippers, but FastCap’s new Magnetic Dust Door makes it easy to pass in and out of the protected space. Magnets in the edge of the door allow it to close and seal on its own, but release easily when someone pushes through. The reusable door allows for a 38-inch opening and fastens along the top and sides with supplied magnetic strips. It’s designed to be used with the manufacturer’s 3rd Hand dust-wall system. ¦ Price: $30 door only; $99 with top and bottom rails; $199 with rails plus two 3rd Hands. 888-443-3748. fastcap.com.
