These Snare Extension Cables are constructed of 3/32" 7x7 galvanized aircraft cable. They are available by the dozen in 3', 6' and 10' lengths. One end has a double ferrule closed loop. The other end has a double ferrule closed loop with an S-Hook for attaching to your snare. These Snare Extension Cables are designed for securing a snare to a tree or post by looping the extension around the tree or post, feeding the end with the S-Hook through the other looped end and then crimping the S-Hook to the snare.
