Frames with Changeable Sign Letters. Easily change your sign anytime you want with our letter kit and slip in track. Corrugated plastic is used as a backing for the plastic tracking to adhere to. The letters are printed and cut on a 1mm PVC material that is flexible enough to bend into the tracks, but sturdy enough to stay there.
This letter kit system is great for businesses that have a message that changes weekly to monthly. I drive past a lawn and garden place in the mornings and they change their message every day to something funny that pertains to the weather.
