Abstract
A railroad crossing gate height adjustment assembly and method for establishing or reestablishing a height of the crossing gate of a railroad crossing gate apparatus. The assembly includes an elongated smooth pipe having a smooth exterior surface and a sliding coupling slidably engageable at a lower end along a length of the smooth pipe. A larger, upper end of the sliding coupling is threadably engageable with a coupling previously secured at a lower end of a wiring conduit of the gate apparatus whereby the length of the wiring conduit is adjustably increased by an exposed length of the smooth pipe. A lower end of the smooth pipe has an external thread which is threadably engageable into a threaded hole formed into a top surface of a gate base of the gate apparatus for supportively receiving a lower end of the smooth pipe.
