Post Caps

To install your Maine Ornamental® decorative post caps, we recommend using an exterior-grade construction adhesive (or PVC glue if attaching to a vinyl post) to adhere the cap to the post. Apply the adhesive liberally to the inside of the cap, and then place the cap firmly over the top of the post.

Solar Post Caps

To activate your new solar post cap:

  1. Remove top by pressing inward on the side of the clear lens, grasping the edge of the top and lifting it off.
  2. Install the batteries.
  3. Replace top by snapping onto side panels. (Ensure the holes in the sides are matched up with the stubs on the top.)
  4. Place your solar post cap in direct sunlight for 24-48 hours to fully charge. Your solar post cap light is now ready to be installed onto your post.

To attach your post cap to the post, apply exterior-grade construction adhesive (or PVC glue if attaching to a vinyl post) to the underside of the post cap before placing the cap firmly on the post.

The solar collector will charge the batteries during the daylight hours and power the light during darkness. Your solar post cap light will stay lit for an average of 6 to 8 hours during the night and turn off during the day, allowing the solar collector to re-charge the batteries.

Solar Classic Post Light:

Discard adaptor from 5x5 base if not needed.

  1. Hold upside down. Note that the clear plastic lens is secured on two sides. Stubs on the underside of the white top fit into holes in two sides of lens. Unsnap the top by pressing inward on one surface of the clear plastic lens and pull away top.
  2. Attach lens unit onto post.
  3. Remove red tab from battery compartment.
  4. Snap cap back onto lens. Ensure that holes in the lens are matched up with the stubs on the top.


Metal Post Caps

Our copper, stainless steel, and brass post caps come with a thin, clear marine lacquer designed to protect them before and during installation. Once exposed to the elements, the sun’s ultraviolet rays, moisture, and pollution begin to break down this coating, exposing the metal underneath. 


In its natural state, copper breaks down in the elements and develops a patina. In general, copper progresses from a natural salmon color to a series of russet browns and grays, and finally to a blue-green or gray-green patina.

Stainless Steel and Brass

Stainless steel has a hard oxide coating which makes it resistant to stains. To maintain this coating clean periodically with a mixture of vinegar and club soda. As with the copper, our brass post caps are protected with a thin clear coating of lacquer. Periodic reapplication of this clear coating will help to protect the brass.

Colored Metal Post Caps

Our Victoria post caps come in a variety of colors, including white, green, real patina, pewter, and black. These colors are a powder-coated, baked-on finish that is extremely hard and durable, rarely requiring maintenance 

Wood Post Caps

As with all wood products, we recommend that you coat these with a high-quality exterior finish to preserve the wood's natural beauty and ensure a lifetime of enjoyment. Apply to all wood areas, including the underside of the cap, before installation.

Glass Post Caps

Exposure to the elements may cause the copper-wrapped solder on your glass post cap to oxidize and lose its original color. Applying car wax before placing the post cap outdoors will help to prevent the initial oxidation. We have found regular furniture polish to have the same affect, but its prevention time may be vary based on geographical location. Reapply the car wax/furniture polish every 3 to 6 months as needed.
