HO Code 83 and Code 100 Track Gauge (KAD343)

An HO-scale die-cast three-point track gauge with a centerline indicator, designed to work with Code 83 and Code 100 rails. Code 83 sits on one side and Code 100 on the other, giving a single tool to verify rail spacing and alignment across the two common HO profiles.

Use during track laying or maintenance to confirm correct gauge and centerline alignment, improving wheel-to-rail fit and overall track performance. The durable die-cast construction withstands frequent use, providing reliable measurements over time.
