The J&K Tool Company Kwik Klamp 1 is the world's most popular patented pipe clamp, load tested to over 3,500 lbs and trusted by well drillers, pump installers, and environmental drillers worldwide for over 40 years.

Key Features:

• 3,500+ lb Load-Tested Capacity: Third-party load tested and certified (Report ESP026328P) to over 3,500 lbs, providing verified holding strength for demanding well drilling and pump installation applications.
• Over-Center Locking Jaw Mechanism: Jaws lock securely when downward pressure is applied to the lever, holding pipe firmly without slipping during operation — with a safety pin that prevents accidental unclamping.
• One-Hand Operation: Brings pipe joints up to easy working level with simple one-hand lever operation, improving efficiency and safety during well service and installation work.
• Fits 1"–2" Pipe in PVC, Stainless, and Galvanized: Accommodates nominal 1" to 2" pipe (1.315" OD to 2.375" OD) in PVC, stainless steel, and galvanized steel. Not for use with bare steel drill rod.
• All-Steel Construction — Made in USA: Lightweight at just 14 lbs, the Kwik Klamp 1 is built entirely of steel and has been manufactured in Wheaton, MN USA for over 40 years under a patented design.

The Kwik Klamp 1 is the go-to pipe clamp for professional well drillers, pump installers, well servicemen, and environmental drillers across the globe. Its patented over-center jaw mechanism delivers reliable, repeatable pipe control with the confidence of third-party load certification — and has earned its reputation as the world's most popular pipe clamp over four decades of field use.

Serrated and hardened replaceable jaws (Part #JK5) ensure lasting grip performance over years of heavy use without replacing the entire clamp. The size adjustment and tension bolt are located inside the front jaw, protecting the mechanism from dirt and water intrusion for reliable operation in muddy, wet field conditions.
