Westpak San Jose recently acquired capstan style grips for tensile testing strapping, webbing, metal ribbon and other samples in our 50kN (11,000 lb.) load frame. The grips have a diameter of 40mm (1.6in.) and width of 80mm (3.1in.).
These grips allow us to better test materials that are weakened by fixturing in traditional wedge-style grips, and are ideal for testing lifting straps, seat belts and other similar materials. The grips are compliant with the ASTM D3950 test standard amongst many others!
Please contact us at here if you would like any additional information or would like a tensile test with these grips.
