The 3" x 7' QSR Zipper allows an entrance or exit to any enclosed area that keeps dust and debris contained within the barrier. By using two zippers approximately 4'-5' apart, one can create a roll-up door to facilitate ease of access, especially useful when carrying equipment or when both hands are occupied. Pairs with a QSR for simple, quick and effective dust containment. For over 50 years, Task Tools has manufactured professional grade tools to contractors and homeowners alike.
