Counterstay for use with series 21, series 21-E or series 22-1-AS
The arms on the counter supports are easy-to-adjust thanks to an internal spring mechanism (size 1 to 3)
The counter support nuts friction resistance is reduced to a minimum as a result of the built-in pressure bearing
Thanks to their support struts, sizes (4 and 5) counter struts are particularly suited for large ball bearings, etc, and ensure that the assembly remains stable during the extraction process
The counter support can be combined with internal extractors and Kukko screw adapters
