Fast, friendly advice from real humans who know their stuff.

Our Internal Square Threaded Adaptors make it easy to convert hollow square metal legs into threaded bases. Whether you're fixing a wobbly bar table or simply adding extra height to your table, these adjustable adaptors give you a secure and lasting fit.

Just tap them into the base of your square leg – the ribbed sides are designed to grip tight and stay put without glue or screws. 

Once installed, you can screw in any 8mm threaded base (like our Self-Leveling Chair Caps) to help stop table wobbles and keep your furniture steady. That means fewer accidental spills, and more confidence when placing hot drinks, meals, or laptops on the surface.

Benefits:

  • Converts square legs into threaded bases

  • Firm, secure grip – no slipping out

  • Perfect fit for tables, chairs & bar furniture

  • Allows easy height adjustment & wobble prevention

 Sizing:

  • 25x25mm External Base – Fits into 22x22mm internal leg

  • 30x30mm External Base – Fits into 25x25mm to 28x28mm internal leg

  • 40x40mm External Base – Fits into 35x35mm to 38x38mm internal leg

  • 50x50mm External Base – Fits into 45x45mm to 48x48mm internal leg

FAQs

Common Questions

What if I order the wrong size?

Your full order is covered by our 30-Day Fit & Satisfaction Guarantee. If the fit is wrong, contact us within 30 days of delivery and return it for a full refund to your original payment method.

Test one piece on one chair and keep the rest unused and in reasonable condition. You pay return postage for a wrong size or change of mind; there are no restocking fees.

How do I choose the correct square adaptor size?

Each option shows the square tube’s outside size first and the compatible internal-opening range in brackets. The adaptor adds an 8mm thread.

  1. Measure the tube’s outside width.
  2. Remove the old insert and measure the hollow opening’s inside width.
  3. Choose the option matching both measurements.

If the tube is between ranges, try a sample pack or send us a photo and both measurements.
