This tool bag is constructed with heavyweight #4 canvas duck. The top opening has a steel frame to keep the bag open and provide security when closed. Two leather straps secure the opening. 2" web handles wrap around the entire bag for added strength. They have a "box X" stitch at the top for extra strength. The bottom is reinforced with heavy vinyl coated nylon and has a double tempered masonite board. Six brass studs are placed on the bottom of the bag to protect against abrasion. There is one inside pocket in this bag. If you don’t see the product you’re looking for, Estex can create it for you to your exact specifications.
