This is a special custom sign made of Extira. Extira is a revolutionary, environmentally friendly panel product. Extira panels are specifically designed and manufactured for exterior use. It resists moisture, rot, and termites. It is twice as strong as MDF, Extira is made to be used outside. This sign has been completely painted.
Note: Extira is heavier then Cedar and therefore costs a lot more to ship.

Here is a picture that shows another option on how to mount a sign to a vertical post. Screw a plate to the end of the sign and then screw the plate to the vertical post.
