The burly Bucket Boss Pro Wrench Roll Tool Organizer is ideal for storing two 15-piece wrench sets, from 1/4 in. to 1 in., in ascending pockets for a precise fit, plus another 10 stubbies. Proper wrench sizes for each pocket are printed right on the canvas, from 1/4 in. to 1 in., and 6 mm to 20 mm. The wrench organizer is 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 tool organizer is secured by two quick-release buckles when rolled, and includes a web carry handle for portability.
