deltoik is a climbing module for children that can be assembled from three different elements. Thanks to its modular system, it can be adjusted to different local conditions and set up in individual dimensions and forms depending on whether it is used on private premises or in a public playground. Offering high flexibility and the possibility for set-ups to be changed from time to time, deltoik makes playing more diversified. Besides the appeal that the device has for children, it also trains motor nerves, agility and strength.
