Black Square Plastic Domed Furniture Tube Insert Cap — Table & Chair Leg End Stopper, 16×16mm to 30×60mm, 15 Sizes

Open square tube ends on furniture legs collect dust, create sharp edge hazards, and leave an unfinished appearance. This black plastic domed furniture tube insert cap presses into the open end of square tube furniture legs — providing a clean, finished appearance, protecting floors from the sharp tube edge, and completing the leg end with a smooth domed profile.

Made from durable black plastic with a smooth domed top surface. Available in 15 sizes covering both square profiles (16×16mm to 30×30mm) and rectangular profiles (20×30mm to 30×60mm). Prices from $2.19 per cap. Suitable for dining chairs, dining tables, office furniture, bar stools, folding chairs, and patio furniture with square tube legs.

Press-fit installation — no tools or adhesive required. The cap inserts into the tube end and is held in place by friction. Removable and reusable.

✅Sizing note: The size listed is the inner dimension of the square tube the cap inserts into — not the outer dimension. Measure the inner width and depth of your furniture leg tube opening accurately before selecting a size. The cap should require light hand pressure to insert and should not rattle once seated.

✅ Key Features of This Square Furniture Tube Insert Cap

  • 🔘Square & Rectangular Tube Fit: Available in both square profiles (16×16mm to 30×30mm) and rectangular profiles (20×30mm to 30×60mm) — covering the most common square and rectangular tube furniture leg dimensions used in dining chairs, tables, and office furniture.
  • 🛡️Floor Protection: The smooth domed plastic base caps the sharp open tube end, preventing the metal tube edge from contacting and scratching hard floors — protecting wood, tile, laminate, stone, and vinyl surfaces.
  • 🔇Noise Reduction: The plastic cap cushions the tube end against hard floors, reducing the scraping and clicking noise of chair and table legs on hard surfaces during normal use and movement.
  • 🧱Durable Plastic Construction: High-quality black plastic resists cracking, fading, and deformation under normal furniture load — maintains its shape and fit over long-term indoor use.
  • 🎨Smooth Domed Top: The domed top profile provides a clean, professional finished appearance to the furniture leg end — more aesthetically refined than a flat cap and easier to wipe clean.
  • 🔧Press-Fit, No Tools Required: Insert the cap into the tube end by hand — no adhesive, screws, or tools required. Removable and reusable if furniture is repositioned or replaced.

❓ Frequently Asked Questions

How do I measure my furniture leg tube to select the correct size?

The size listed is the inner dimension of the square or rectangular tube opening — not the outer leg dimension. Use calipers or a ruler to measure the inner width and depth of the tube opening at the bottom of the furniture leg. Select the size that matches your inner tube dimensions. The cap should require light hand pressure to insert and should not rattle or move once seated.

What is the difference between the square and rectangular sizes?

Square sizes (16×16mm to 30×30mm) are for furniture legs with equal width and depth tube openings. Rectangular sizes (20×30mm to 30×60mm) are for furniture legs with unequal width and depth — for example, a leg that is 20mm wide and 40mm deep. Measure both dimensions of your tube opening to determine whether you need a square or rectangular cap.

Will this cap scratch my floors?

No — the smooth domed plastic cap covers the sharp metal tube edge and provides a non-marking contact surface. The plastic material does not scratch hard floors under normal furniture use. For additional floor protection and anti-slip grip, consider pairing with self-adhesive rubber feet pads applied to the base of the cap.

Can the cap be removed and reused?

Yes — the press-fit design is removable. Insert a flat tool (such as a flathead screwdriver) between the cap flange and the tube end face and lever the cap out. The cap can typically be reused provided it has not been damaged during removal.

Is this cap suitable for outdoor furniture?

These caps are suitable for sheltered outdoor use. Durable plastic resists moisture and will not rust or corrode. However, prolonged direct UV exposure may cause gradual discoloration over time. For fully outdoor applications with direct sun exposure, check for UV-stabilized alternatives.
