Scissor tensile grips utilize a self-tightening pantograph linkage to maintain continuous, slip-free clamping force on flexible elastomeric specimens as they thin under load.
Featuring cross-linked mechanical arms, scissor grips automatically increase horizontal clamping force in direct proportion to the applied tensile load. This self-adjusting mechanism prevents sample slippage during high-elongation testing of materials like rubbers, elastomers, flexible polymers, heavy plastic slabs, and textile webs.
Designed for rapid specimen insertion, scissor tensile grips ensure true axial alignment across universal testing machines and support international standards such as ASTM D412, ASTM D638, and ISO 37.
