These webbing capstan grips incorporate an ingenious double capstan design which provides fast, easy loading with a gripping action that results in proper breaks in the full gauge length of the specimen.
The key to the ease of loading is the use of an inner and outer capstan.
The specimen is loaded simply by inserting one end into the groove of the inner capstan and cranking it through 360 degrees.
Gripping efficiency is also greatly increased because the surfaces of both capstans are utilized.
