Double Gate Packages

Each package in this section contains hardware to hang a set
of double wooden gates: a gate latch for the operable gate,
six heavy duty ball-bearing butt hinges,
dummy gate handle for the inactive gate, and a gate stop.
  

Double gates will also need a cane bolt, 
which holds the inactive gate firmly to the ground.
