Precision wedge block Size 85mm

Centring hole Ø 12 mm. Case-hardened steel and fine-machined wedge surfaces. A spherical attachment no. 6440 is included with every precision whipstock. The fine-machined wedge surfaces permits a smooth, precise adjustment to less than 1/10 mm. Operation can be via an open-ended spanner - hence ensuring enhanced safety and ease of handling due to the large adjusting forces.
