The Kadee three-point track gauge is a must - have for HO scale model railway enthusiasts. It's die - cast and comes with a centerline indicator. One side is designed for Code 70 rail, and the other side is for Code 100 rail, offering great versatility.

Using this Kadee track gauge is easy. Just place it on the track to measure whether the gauge of your Code 70 or Code 100 HO scale track is correct. Make sure to align the centerline indicator with the center of the track for accurate measurement. When not in use, store it in a dry place to prevent rusting. Clean it gently with a soft cloth if it gets dirty. Avoid dropping or hitting it hard, as this could damage the precision of the gauge.
