Instron® 2715-003 Series Webbing Capstan Tensile Grips

These grips are designed to permit predetermination of specimen length, and allow quick, convenient loading. They incorporate an ingenious double capstan design which provides for fast, easy loading together with a gripping action that results in proper breaks in the full gauge length of the specimen. A split capstan has been arranged so that it can be rotated within a completely separate outer capstan. To load a specimen simply insert an end into the inner split capstan and then rotate this through 360°, and lock in position. This distributes the load over both the inner and outer capstan, thereby minimizing failures at the bite.
