This is a replacement stopper/knob for the Rooster Carbon Tiller Extensions.

Make sure you select the correct stopper for your tiller extension:

The Small stopper will fit the 19mm sections.

The Large stopper will fit the 22mm sections.

The X-Large stopper will fit the 25mm sections.

When reattaching your new Rooster knob, be sure to clean the carbon end. Then use some marine grade adhesive or strong marine super glue.
