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.

The glass is beautiful, when light hits it the black seems lighter. It’s well made, I use it for our gate posts its attractive easy to put on and they stay put. Ours fit perfectly and were not loose at all. If you want a new stunning look I would suggest these caps.
