K4 Deep Tuttle Spacer
Windsurfing fin spacer. Safely use Tuttle fins in a Deep Tuttle box with this spacer to fill the void.
In theory, Tuttle fins should fit into a Deep Tuttle box with no problems (as the dimensions of a Tuttle fin head should be exactly the same as a Deep Tuttle fin head, with about 12mm less material on the top). In reality, when tightening the fin bolts, the shorter Tuttle head can get pulled into the box a little too far. This can result in the fin head not being flush with the bottom of the board. The K4 Deep Tuttle Spacer can help to avoid this problem.
Available in iconic K4 YELLOW or BLACK.
(Please note that this spacer needs to be a little bit loose in the fin box to allow it to sit as far in as possible and to enable it out to come out easily after use. So, depending on which board you are using it with (yes, there may be slight variations of the dimensions of Tuttle boxes within different windsurfing boards and brands!), the spacer may need to be sanded down a little with sandpaper wrapped around a sanding block or a small, flat piece of wood.)
