This releasable rubber joint for 20 mm tiller extionsions contains the same base and rubber rope core joint as our 652950 joint but comes with a longer mounting pin and a wider heat shrinkable black x-gripped tubing.
 
The rope core will avoid complete failure should the rubber tear. Mounted with pin which is kept in place by a piece of heat shrinkable tubing. The distance between the mounting hole centers of all joints is 32 mm. To remove a joint: simply cut off the tubing and push the pin out.
