All wood post cap finials are constructed of laminated clear, redwood and western red cedar. They should be sealed before installation with an oil based primer, paint, stain, or preservative to ensure a long life.
Finials are pre-drilled and are shipped with lag screws for easy installation after sealing. The screws should be inserted first into the base of the wood finial using a pair of pliers around the smooth section (not the threads). Then thread the finial (with mounted lag screw) into the wood post. Pre-drilling the top is optional and may aid in the installation. Exterior caulking material can be applied to the base to ensure a tight fit if desired.
All finials must have a proper sealer and/or paint applied to prevent cracking!
