The Wrench Roll is ideal for storing and organizing 11-piece wrench sets from 1/4 in. to 1 in., or 6 mm to 25 mm, in descending sized pockets for precise fit. Made from heavy-duty Duckwear canvas, which is preferred over polyester because the canvas will absorb tool oil over time like a well-oiled baseball glove. Polyester tool rolls tend to turn into oil slicks. The Wrench Roll is secured by fabric ties when rolled.
