Here are two pictures of the standoff insulators I found on the internet. These were made of crystal clear glass with a lag to screw into wood. I'm assuming the purple one was in the sunlight a lot to change color. I've seen these come up for sale from time to time and would love to find one. Even though I'm a porcelain man I still like glass too. If anyone has any of these or for sale I'd love to see any pictures or info on them.
