A patented closed cell + high friction rubber seal. Foam-rubber seal type A1. Packed in a full-color box.
With continuous usages the seals wear out. When the GRABO seal finally wears out, the lifting capacity diminishes. In this case you can replace the worn seal by hand within seconds. You can use the spare one supplied with the kit. This patented high friction foam-rubber seal fits all GRABO models.
