Kadee Coupler Trip Pin Pliers are a must - have for model train enthusiasts. These pliers work for all scales from HOn3 to O scale. Specifically designed for HO and HOn3 couplers, they let you adjust trip pins to the perfect height with a gentle squeeze. The curved jaw surfaces are a great feature as they prevent trip pins from kinking when you're bending or straightening them.

To use these Kadee Coupler Trip Pin Pliers, first identify the trip pin on your HO or HOn3 coupler. Then, gently squeeze the pliers around the trip pin to adjust it to the correct height. When bending or straightening the trip pin, make sure to do it slowly to take full advantage of the curved jaw surfaces and avoid kinking. As for maintenance, keep the pliers clean and dry after each use. You can wipe them with a soft cloth. If they seem a bit stiff, you can apply a small amount of lubricant to the pivot point. Store them in a dry place to prevent rusting.
