These external PVC feet fit over the ends of round tubes and furniture legs. They provide a neat finish and help protect floors from scratches caused by exposed tube ends.
Also known as round chair leg caps, external tube caps or replacement furniture feet, these PVC ferrules fit over the outside of matching round legs and tubes. Both listed sizes are black.
Choose from nominal sizes of 20 mm and 25 mm for suitable round chair and table legs, including as replacements for worn or damaged feet. Check the tube diameter and the dimensions below before choosing your size.
Made from PVC plastic. These are external ferrules that fit over the tube, rather than ribbed inserts that fit inside it.
No minimum order: buy from just one ferrule. Select your required size in the product options above, then choose the quantity you need.
Measure the outside diameter of the bare tube or leg. Measure straight across its centre, from one outer edge to the other. Do not measure over an existing foot.
For example, a round tube measuring 20 mm across the outside corresponds to the nominal 20 mm ferrule option. Compare the remaining dimensions in the table to check that the ferrule is suitable for your application.
The letter d on the drawing identifies the ferrule’s internal diameter. The nominal size and the listed internal diameter are slightly different: the 20 mm option has a listed internal diameter of 19.9 mm, while the 25 mm option has a listed internal diameter of 24.9 mm.
Keep the ruler or tape straight across the centre of the tube. If you start at the 10 cm mark, subtract 10 cm from the final reading. For example, a reading from 10 cm to 12 cm gives a diameter of 2 cm, or 20 mm.
Callipers make small differences easier to measure. For these external ferrules, choose by the tube’s outside diameter, not its internal opening.
All dimensions are in millimetres. The first column shows the nominal ferrule size. The letter d is the internal diameter of the ferrule; H, h and D refer to the dimensions marked on the drawing.
| Type | Nominal size (mm) | Choose colour | Internal diameter d (mm) | H (mm) | h (mm) | D (mm) |
|---|---|---|---|---|---|---|
| Round PVC Ferrule | 20 | Black | 19.9 | 30.0 | 24.0 | 26.0 |
| Round PVC Ferrule | 25 | Black | 24.9 | 36.0 | 29.5 | 32.0 |
Remove the old foot and check that the tube end is clean and free from sharp burrs. Fit the ferrule over the outside of the tube and press it on until fully seated.
Check that each foot is secure and that the furniture stands evenly before use. Do not use extra force to compensate for an incorrectly selected size.
If you are unsure which size to choose, contact TREBORK with the outside diameter of the tube and a clear photograph of the leg end.
