Dr-Shrink has a wide array of sizes and colors in shrink-wrap zippered access doors. You can choose from 3 different colors and sizes. Colors come in Blue, White, and Clear. Sizes come in 36" x 72", 30" x 48", and 36" x 48". Access doors are used for entry into the shrink-wrap enclosure without actually cutting the shrink-wrap. This is very useful for off season access aboard your boat.
