Product Details
The kit is designed for use with Series 21 and Series 21-E, as well as Series 22-1-AS specifically for models 22-1 and 22-2. It includes a counter support that can be combined with internal extractors and Kukko screw adapters, with nearly all components available as replacement parts, streamlined by a numbering system for time-saving orders. The arms of the counter supports are easily adjustable due to an internal spring mechanism, with sizes ranging from 1 to 3. The friction resistance of the counter support nuts is minimized thanks to a built-in pressure bearing for sizes 2 to 5. Furthermore, sizes 4 and 5 are particularly suitable for large ball bearings due to their support struts, which ensure stable assembly during the extraction process. The kit is equipped with a mechanical pressure screw and requires the use of a protective blanket and goggles. Specifications include a support surface of 14 x 18 mm, a counterstay reach of 165 mm, and a spread counter support of 100 mm.
