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. Alternatively you can buy as many from any of the distributors or retailers. This patented high friction foam-rubber seal fits all GRABO models.
