Prominent grooved parts of the cube, which are located at different heights on each of the 4 corners of the “cube” (tab #1 to #4, #1 being the lowest and #4, the highest). These tabs are an integral part of the Candock system. When ralied in groups of 4, the cubes create a larger square. At the center of this square, 4 different tabs overlap each other. These tabs form a single opening and are meant to be coupled with our CANDOCK SLIDING NUT and G2 or G1 CONNCETING PIN to form a unique structure.
These watertight plugs are always found on the side of the cube that isbetween tab # 1 and # 4. These plugs, made of breathable material on the G2 line, act as pressure release valves thus preventing any cube deformation which is due to temperature or altitude.Furthermore, these plugs prevent any condensation inside the cube. On the other hand, some older prodcutions of the G1 line are not equipped with our most advanced breathable plugs, they are simply scealed with regular blag plugs.
