Double wire locks are used when you are building your own cleats. Instead of tying nylon, wire or fluorocarbon, these locks are available to lock the connections. Tighten with wire cutters or regular pliers. Feel free to pinch at three points on the lock for best strength. Also, do not pinch too hard so you damage the material. Can be used for wire, fluorocarbon and nylon. Available in different dimensions so try to use locks that are adapted to the thickness of your material. See table below. Supplied in packs of 20 Available in the following sizes: 0.7 mm 1.0 mm 1.5 mm 1.8 mm
