The MB-1216-JC Body Grip Trap is the same Megabear trap that was developed and produced by John Caretti of Michigan. MB has worked with Mr. Caretti to ensure that his record of excellence is maintained. The Megabear has the strongest springs on the market and is the only body grip trap with full 3/8" jaws and striker bars. This trap has the MB safety hooks that stay where you put them and a tension adjustable trigger. The Megabear is extra heavy duty from top to bottom. At 12" high and 16" wide the Megabear will fill many channels and streams with minimal blocking. As with all large body grip traps, the use of a body grip safety grip is strongly encouraged for personal safety.
