This is a safe foot snare which is designed for catching animals for biological study and zoo specimens. Also useful for unmarred fur-taking and problem wildlife control. The spring mechanism is made of oil-tempered spring steel, wound and retempered to provide fast action. The throw cable for cougar and black bear is a 3/16" x 48" galvanized airplane cable (GAC). The grizzly and polar bear throw cable is a 1/4" x 60" galvanized airplane cable (GAC). All anchor cables are 1/4" in diameter and come complete with choker end for simple and secure tie-up, and 5/16" swivel. Our locking slides are now tumble polished to de-burr and remove sharp edges.
