The JDC universal tiller extension is a removable machined socket that houses a swiveling rope-core urethane joint by WinDesign. The joint swivels smoothly from any angle and with zero play, eliminating the twisting loads that cause universal failure, while also allowing you to keep a good grip on the stick during tacks and jibes.
It is adaptable to 25/32 in. (20mm)-diameter tiller extensions and fastens with a single screw. This extension adds 2 in. in length to the existing shaft.
