This super heavy-duty vise uses a new approach to holding large hooks, called a Large Iron Retention System. It will hold hooks up to the largest size on the market with a positive grip, not relying on friction like conventional vise jaws. The system also allows heavier force on the stronger thread now available; the vise's grip on the hook is no longer a limitation on the amount of winding force that can be used. The head of the vise rotates 360 degrees for complete access to all sides of the fly and comes with a powder coated oversized base for maximum stability. The base also includes mounting holes for fastening to your bench, as well as accessory post holes and a material/hook pocket. Special order item, allow 1-2 weeks for delivery.
