Wooden Gate #25 as a double gate in upstate Michigan.

As a note, #25 is offered to a maximum 60" height. For gates taller than 60", we introduce what are called Pattern Blocks, joined between the pickets to stabilize them from probably bowing and cupping. An example of this can be seen on Gate style #57.  The other option is to add a mid-rail separating upper and lower pickets.
