Estex Compression tool and bolt cutter bags are made from heavyweight vinyl coated nylon with a heavy bottom reinforcement for additional support. This version has five pockets for compression tools and bolt cutters. The pockets have a hard plastic backing so the tools do not cut through the back fabric when removing them from the bag. Some linemen will put "D" dies in one tool and "O" dies in another so they don't have to change dies while on the job. The top edge is reinforced with leather to prevent abrasion to the top edge when tools are removed or replaced. There are also 2 grommets for attachment with bucket hooks.
