K4: New covers for empty fin boxesPhoto: Hersteller

Covers for unused fin boxes are now available from K4 Fins. The range includes blankers for slot boxes, US boxes and mini tuttle boxes. There are also placeholders for deep tuttle boxes.

Not bad, but not ideal either: if individual boxes on multifin boards are not used, the open fin boxes cause turbulence. This can have a noticeable effect on riding behaviour, as we have just seen with the test of the We One We Style Wave . Many manufacturers supply the corresponding covers with the boards, but some boards come without covers - or the parts are lost over time.

K4 now offers a selection of covers for Slotboxes, Mini-Tuttle and US boxes. The slot box and US versions are available in two different sizes, all in K4's typical yellow or black colour for 5.75 per pair.

  • K4 Slotbox Blanker 90mm
  • K4 Slotbox Blanker 130mm
  • K4 Mini-Tuttle Blanker
  • K4 US-Box Blanker 130mm
  • K4 US-Box Blanker 205mm

K4 also offers a Deep Tuttle Spacer, which can be used to compensate for the difference between a normal Tuttlebox fin and a Deep Tuttle fin box. This is also available in yellow and black and costs €10.00.

K4 Fins made a name for themselves a few years ago with relatively inexpensive but good plastic fins in the wave sector; the yellow track holders are instantly recognisable. The British company now also works with fibreglass-reinforced plastics to achieve different degrees of hardness and to be able to offer longer fins.
