Coupler Trip Pin Pliers
For HOn3, HO, S, On3 & O Scale Couplers. Adjust the trip pin to the correct height by gently squeezing it with these specially designed pliers. The pliers have jaw surfaces that are curved and smooth. Adjusting the height of your Coupler Trip Pins is easier because the plier's surfaces conform to the bend of the trip pins and prevent them from kinking when bending or straightening.
