The Single Stake Swivel with a #6 J-hook is used for anchoring traps and the Collarum cable restraint with a single rebar stake that is 1/2" in diameter or less. It is effectively used for animals such as raccoon, fox, skunk, etc. The length of the rebar stake is determined by the soil conditions, i.e. solid soil perhaps 15" - 20" length, while sandy soil conditions may require 24" + in length. A single stake is not typically suitable for anchoring coyote traps or traps set for larger sized animals.
