  300 & 500 models
The 300 model and very similar 500 model were each made in two V.O. sizes; 4" and 5". The breakaway traffic feature is achieved by virtue of a breakable cast lug on each bolt that draws up against a snap ring in the top of the lower barrel; and bottoms against the bottom of the upper barrel.
  • These models have only the "Dresser" name cast onto the upper barrel; with no mention of M&H.
  • The V.O. size and model number are cast onto the barrel.
  • 202163 is also cast onto the barrel; this refers to a (design) patent. Another patent, 3,505,027 was taken out for this hydrant design but is not referenced on the hydrant itself.

    This is the Traffic 300 model.
