Hog Rings are used to securely attach bird control netting to cable perimeters systems. Hog Rings can also be used to attach net accessory items such as net zippers and patch minor tears in netting. Hog ring magazines load easily and quickly into the pneumatic tool. Hog Rings come in a ‘C’ shape with sharp points to pierce surfaces when crimped. Once the ring is crimped with a hog ring tool the shape will change to an ‘O’ ring. Pneumatic Hog Rings come in 10,000 per box and are available in galvanized or stainless steel material.
