This is a sale for 3 Freedom Brand Dog Proof Trap. This 1 trap is the FB1 model which is a push/pull trigger system, but to set them it is very easy all you have to do is push the plate down and you will hear a click and its set. This trap must be cleaned after every catch as the dirt can affect the setting. Once cleaned out it can be used over and over again. These traps are made right here in the USA. Any questions please ask.
