There are multiple ways to install but as a general rule the bigger slab signs go on posts and the smaller signs attach to a fence/gate or a house. We sell installation kits for the bigger signs which come with brackets, screws and attachments for $89. For smaller signs you can use screws, glue, eyes and hooks, chain or a bracket. We send all out signs blank so you can choose any mounting option you like. Tip: Remember to pre-drill a pilot hole to prevent chipping.
