Review on Plastic Square Tubing Inserts: Enhanced Industrial Hardware and Biscuit & Plug Accessories by John Mejia

Not much to say about this item other than it works exactly as advertised. They sit nice and tidy on my steel fence posts, just in time for the rainy season here in Arizona. They're made of durable plastic and look good enough to keep water off my bars, which was my main concern. They're not pretty, but they do their job. I'll be revisiting this review after enduring these post stubs for a few months in the Arizona sun. I think the plastic will fade and crack in Arizona's dry heat and unrelenting sunlight, but I'm prepared to be pleasantly surprised if they hold up.
