When you replace the factory clips on your planer boards, snap weights, etc. with the Church Tackle Lock-Jaw Clip, you can be sure that your line, no matter how thin or slick, will slip free. This is the strongest-holding clip available, with an advanced pad that firmly holds all lines, from braid to copper. Simply twist the lever to lock it down; use a screwdriver with a light touch to increase or lessen the clamping pressure as desired. Flip the lever again to release.
