These 2x3 inch rectangular tubing plugs are exactly what you need to cap off open ends on metal frames, furniture legs, railings, or gates.

They're made from tough LDPE (low-density polyethylene) that stands up to wear, moisture, and temperature changes from -94°F all the way up to 175°F.

They're designed to fit tubing with wall thicknesses in the 10 to 14 gauge range, so they hold snug without being too loose or too tight.

Just push them in by hand—no glue, no tools, no complicated steps.

They stay put and give your project a clean, finished look.

These plugs aren't just for looks.

They keep dust, moisture, and bugs out of the tubing, which helps prevent rust and corrosion inside the tube.

That's a big deal if your project lives outside or in a damp workshop.

The matte black finish blends nicely with most metal finishes, whether you're working with steel, aluminum, or iron.

They're versatile enough for industrial applications, DIY furniture, or even art projects.

Each pack gives you 8 plugs, so you can cap multiple pieces or keep extras for future projects.
