The CAPTER® is a solution to retrieve cambium savers when one ring has a diameter larger than 30 mm.
It is made of solid beechwood in France, and developed to be placed on any retrieval ball with a diameter equal to or less than 30 mm and a string of at least 12 cm.
This way, cambium savers can be adapted, for instance a JOKER LIGHT with no rings but used with two carabiners.
