kiwi cross system
Developed in New Zealand, the unique attachment point system is incorporated throughout to allow for your own specific storage needs. The ability to swap adapters around means rapid changeovers between sports or everyday campervan essentials. Oars, paddles, and longer items can be suspended from the ceiling using the same system.
We can design and make adapters to your own requirements. Simply come to us with what needs securing and we will discuss how to make it a reality.
