Guillotine Trap Door Trigger

Guillotine or sliding drop gates use a trip wire to trigger the door to fall.

Therefore it is extremely important that the trap be strategically baited to insure that most if not all of the pigs in a sounder have entered the trap. Rooter lifting gates require that a hog use its nose. I personally prefer the guillotine door as it generally has a bigger opening and it is positively closed with an active latch to prevent pigs from rooting.
This is not a continuous trapping door once it s closed it s closed until you come and manually open it or reset it. Guillotine or drop style doors are called single catch doors because once the trap has sprung that is the door has closed no more animals can enter the trap until it is manually reset.
