No.205 Kadee height gauge.

The No.205 height gauge is an essential item for checking and maintaining your Kadees at the correct height for smooth and efficient operation. It also checks the height of the trip pin and the platform mounting height which can be used to see if there is enough clearance in the buffer beam area of stock and locos. It is made of metal, so will cause a short if used on track with a power supply switched on.
