Round Tubing Inserts

RTI Series round tubing inserts are finishing plugs that companies across industries can use in a variety of round applications. These durable finishing plugs for round tubing create a professional look and protect surfaces from damage during assembly and use. They help with unfinished furniture items as well as unsightly pieces of equipment.

These round finishing plugs have external tapered ribs to ensure a secure fit in a wide range of tubing gauges. Designers rely on these components to enhance structural integrity, minimize rattling, and ensure each connection point maintains a smooth, uniform finish.

They also have a subtle yet stylish design, making them the perfect way to put a sleek touch on a project or cover up any unattractive inner components. Our plastic end plugs for round tubing simplify installation and provide long-lasting performance across manufacturing, construction, and furniture applications.
