If you are building a retaining wall or stacking cages over 1m high please use "C" rings or spirals. The U Clip is secured by using a special tool available for purchase or hire. Alternatively they can be fastened using needle nosed pliers. One box of U Clips contains 2160 clips. Clips should be used every 150mm - 200mm, all around the gabion basket.
U Clips are made from Stainless Steel. These clips are collated for use in pneumatic tools, but may be broken off in singles to allow connections using U Clip tool or pliers.
