Grampo de aperto em aço BESSEY GH25 com alavanca 250 x 120 mm

The BESSEY GH25 is a steel lever arm clamp built for high-volume production, delivering up to 8,500 N of clamping force with a 250 mm jaw opening and 120 mm throat depth. Its quick-acting lever mechanism tightens and releases up to 5x faster than conventional screw clamps, making it ideal for assembly, welding, and metalworking.

Advantages

Ergonomic lever handle reduces hand fatigue during repetitive clamping. All-steel construction with galvanized finish resists corrosion and withstands vibration, maintaining grip even under dynamic loads. Fixed and sliding jaws provide stable, parallel clamping across the full 250 mm capacity. Trapezoidal thread on the spindle allows fine adjustment of clamping pressure after quick lever closure.

Suitable for

• Metalworking and welding fixtures
• Woodworking and cabinet assembly
• Jig and fixture building
• High-volume production clamping
• Maintenance and repair tasks
