Fits all coil spring and long spring traps. It is the easiest way to raise or lower trap pans. You just slip the adjuster over the trap's cross frame (where the dog is attached). To raise the pan, pull away from the trap on the adjuster's handle. To lower the pan, push the adjuster's handle toward the trap. Once you use this tool, you will never be without one again. Precision cast from tool steel and zinc plated to retard rust.
