A five‑blade hand crimper engineered to form factory-precision corrugations on duct, stovepipe, gutter, and downspout ends for tight-fitting joints

1‑5/8″ throat depth corrugates sheet metal up to 41 mm deep—perfect for seamless insertion

Hardened steel blades deliver long-lasting durability and crisp, consistent crimps 

Heavy-duty, heat-treated steel handles resist bending under hand pressure for reliable leverage 

KUSH’N‑POWER® compound‑leverage handles amplify force (around 8:1 ratio) while giving a soft, slip-resistant grip for easy one‑hand operation and reduced fatigue 

Ambidextrous design works smoothly with either hand—great for tight spots or lefties

Designed for speed, ease, and safety—reproduces factory pre‑forms, reduces effort, and eliminates handle flex

Proudly made in the USA with quality craftsmanship
