Push-pull toggle clamp (Knebelklemme) designed for safe, simple and comfortable clamping Key benefits Reliable hold: Lever-controlled push-pull action locks firmly and resists lateral forces, preventing accidental release from side thrust. Easy operation: One-handed, comfortable lever movement for fast, repeatable clamping and unclamping. Durable construction: Made from alloy steel to provide long service life and dependable performance in workshop conditions. Compact design: Small footprint fits tight fixtures and bench setups without obstructing work. What it does and who it’s for Securely holds sheet metal and printed circuit boards (PCBs) during processing. Ideal for use wherever a compact, dependable clamp is needed: welding fixtures, jigs, repair benches, and assembly stations. Four model choices let you pick the best fit for your application: GH-304C, GH-304E, GH-305C, GH-305E. Features and compatibility Controlled lever action during clamping prevents unintended movement from side loads. Simple, reliable mechanism compatible with common shop and bench tasks involving metal sheets and PCBs. Robust alloy steel body delivers consistent clamping force and long-term reliability. Practical use scenarios Welding: Hold sheet metal in place in a fixture while welding to maintain alignment and resist heat and vibration. Jigging and assembly: Secure parts for drilling, routing, or fastening operations to improve repeatability and safety. Electronics repair and assembly: Clamp PCBs for soldering, inspection or testing without movement or damage. Models: GH-304C, GH-304E, GH-305C, GH-305E — choose the model that matches your mounting and application needs.
