The specimen is folded around the knurled roller to give maximum contact area. As a load is applied to the specimen the cam self-tightens, spreading the load evenly around the cam and against the serrated body of the grip.
Used for slippy specimens where a serrated surface is necessary to bite into the material and prevent slippage.

Serrated surface on the contact face of grip body
Clamping width 45mm,
Specimen thickness 0 – 5 mm
