Control the wild hog population with the Hog Slammer™ one way gate! Assemble a pen using the Hog Slammer™ gate as the point of entry (materials for assembling pen not included). Hogs enter the pen through the adjustable saloon-style doors. A trigger rod holds the doors open until the hogs knock over a bucket of bait inside the pen. Once the doors are shut, the trapped hogs cannot escape. A bag of hog attractant is included.
