Review on 🔩 Industrial Hardware and Biscuits & Plugs: Durable Square Plastic Tubing by Prescott Plastics by Fred Griffin

I recently sanded and repainted some 1920's outdoor railings. I had to replace the top railing covers as time had eroded. I couldn't find anything that would fit 7/8" at my local hardware stores. These plastic caps were absolutely perfect. It fits very snugly to the railing and doesn't let water through. Very happy with my purchase.
