Ergonomic handle for woodworking: The handle is shaped for comfortable, secure gripping, making the claw clamp easy to use for holding, pulling, or positioning workpieces during carpentry and DIY tasks. Durable iron construction for lab stands: The lab stand clamp is made of iron that resists deformation and reduces the risk of rust, providing a stable, long-lasting mount for laboratory apparatus. Adjustment is simple and precise with the jaw mechanism. Sturdy laboratory/test tube clamp: Built to be practical and robust, the laboratory clamp resists damage and breakage under regular use, providing reliable support for test tubes and other small glassware. Corrosion-resistant jaw finish: The adjust jaw clamp has an electroplated surface treatment to improve corrosion resistance and extend service life in environments that may expose clamps to moisture or chemicals. Key functions and compatibility Claw clamp: Designed for woodworking tasks that require gripping, pulling, or holding small components securely. Adjust jaw clamp: Provides controlled tightening and positioning for lab apparatus on a stand. Test tube clamp: Compatible with common test tubes and laboratory stand setups for experiments, heating, or storage. Practical benefits — why you need it Safer, more controlled work: Ergonomic grip and secure clamping reduce slips and improve precision for both workshop and lab tasks. Long service life: Iron construction and electroplated jaws resist deformation, rust, and corrosion for dependable, repeatable performance. Easy to use and adjust: Simple adjustment mechanisms let you position and tighten quickly without tools, saving time during setup. Typical applications 1. Woodworking and repair: Hold small boards, trim pieces, or components steady for cutting, sanding, or fastening with the claw clamp. 2. Laboratory experiments: Secure test tubes, small flasks, or tubing to a lab stand for heating, titration, or observation using the adjust jaw/test tube clamp. 3. Classroom and demonstration setups: Fast, reliable mounting of apparatus for teaching labs or demonstrations where repeated setup and teardown are required.
