The Bucket Boss Big Wrench Roll Tool Organizer is ideal for storing and organizing 5-piece wrench sets from 15/16 in. to 1.25 in., or 22 mm to 32 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.
