The Church Tackle Lock-Jaw Clip fits the TX-12, TX-22, TX-44 and the Walleye Board planer boards from Church Tackle. It is also designed to fit side planers made by other companies as well as drop-weights and many other applications. The replaceable pads hold  great on all lines including mono, super braids, power pro, lead, wire, and copper lines while not damaging the line. The Church Tackle Lock-Jaw Clip is designed without a spring that could possibly weaken or lose tension. The clip clamps down with a simple twist of the lever and only fine adjustments are needed for more or less clamping pressure.
