Features and Benefits:

• 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
