The Peak Rotary Vise is crafted for optimal fly-tying efficiency and easy adjustment. It's built to last with materials like stainless steel, brass, and aircraft aluminum. Hardened tool steel jaws securely hold hooks from size 2/0 down to the smallest. The C-Clamp mounting vise outperforms competitors, offering a grip range of 2-1/4" to 11/16" by reversing the lower rabbeted jaw. Precision guide rods keep jaw faces parallel, preventing table damage. A large, comfortable tri-lobal screw is used for adjusting the clamp. The deep rabbeted jaw ensures stability on rounded table edges. It's the most stable, versatile, and robust clamp, compatible with accessory posts.
