This is a air
brake/treadle valve holding tool. This tool was manufactured to hold two treadle valves so
that the attaching air pressure fittings can be exchanged from the old
valve to the new valve. When holding the two valves side by side, the
same exact angle of the pressure fitting can be attained. Some of these
valves can have up to eight or more pressure lines with check valves.
The tool has been blanchard ground flat and comes with attaching
hardware.
