Did you know? These cobalt blue glass post caps are made of vibrant blue glass. It’s not an insert or finish, the glass is blue so the deep, rich color holds up beautifully over many years.
Durable, long-lasting glass.
These cobalt blue glass post caps are highly durable and visually appealing. Made with ¼-inch heavy-duty glass and strengthened with a classic pyramid top shape, the caps resist cracking, even in extreme hot and cold weather conditions.
Protect your posts.
Eliminate rain and moisture from seeping into the top of your posts, helping your posts last longer and avoid rotting, bowing, and bending – so they look better and perform longer.

Easy to install.
Run a bead of clear adhesive silicone, available at any home improvement store, around the top of your post to adhere the glass posts caps to your posts. That’s it — easy.
Safe indoors or outdoors.
These cobalt blue glass post caps work well for backyard spaces like decks, patios, porches, fences, pool enclosures, and even mailbox posts. You can also use them indoors on staircase newels and bedposts.
