Kadee #237 Coupler Trip Pin Pliers
From Kadee:
For HOn3, HO, S, On3 & O Scale Couplers. Adjust trip pin to the correct height by gently squeezing 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 pliers surfaces conform to the bend of the trip pins and prevent them from kinking when bending or straightening.
Bend down feature only for use on S, On3 & O Scale couplers.
Package Includes:
(1) Coupler Trip Pin Pliers for HOn3 to O Scale
