205 Coupler Height Gauge Ho (KAD205)

The HO Coupler Height Gauge is an essential tool for HO-scale model railroading, helping you set the correct coupler height, accurately gauge the trip pin height above the rails, and establish permanent uncoupler heights for reliable operation. It also includes a built-in HO track gauge to verify alignment as you work, taking the guesswork out of coupler setup.

Four tools in one, it provides an instant visual reference for proper coupler height, an accurate trip pin height measurement, a built-in track gauge, and a movable dowel that tests Kadee Magne-Matic uncoupler height and records the adjustments needed. Ideal for building or upgrading HO layouts, it helps maintain consistent coupling performance across rolling stock and decoupling infrastructure.
