Review on 🔲 Prescott Plastics : Square Plastic Tubing for Industrial Biscuits & Plugs by Tone Hatton

I used these as plugs for my 3" tubular steel gate posts. They were easy to install. A few hammer blows and you're done! Just make sure you know the inside diameter of the square tube before placing an order - it depends. To top it off (no pun intended), it improved my project with the protection and professional look I was looking for. I highly recommend it!
