50mm Round Ribbed Full Dome Tube Insert

These 50mm domed round ribbed tube inserts are designed to provide a clean, secure finish for hollow round tubes and pipes. The tops of these inserts are a Full Dome (Half Sphere) and are designed to act as feet for hollow tubular angled legs on chairs and tables, with the pronounced dome meaning you don't have to worry about a pre-set angle, as the dome will cater for any angle.  The domed feature on these will also add an element of decorative detail, to what would otherwise just be a regular flat insert.

The head diameter is designed to sit flush with the outside of the tube whilst the shank has flexible horizontal ribs to suit a multitude of tube walls, in a range of both metric and imperial sizes.  Thanks to the flexible lateral ribs running around the shank of the insert, they should be suitable for tube wall thickness of between 1 to 2mm metric (14-20 gauge imperial), unless otherwise stated. 

Manufactured from durable LDPE plastic, they are commonly used as protective end caps, tube feet, and finishing plugs across furniture, fabrication, and light industrial applications. They're designed to retain themselves inside tube, with the head sitting over the outer ends of the tube or pipe, sitting flush with the outside circumference of the tube and providing a neat finished appearance.

Key Features:

• Fits hollow tube or pipe with a 50mm outer / external dimension
• Manufactured from resilient LDPE
• Ribbed design for secure fitting
• Helps protect floors from exposed tube ends, reducing noise and marking
• Available in multiple colours
• Designed primarily for indoor use but can be used outside but not UV stabilised as standard
• Enhanced head profile, providing a spherical / domed appearance

Technical Information:

• Tube or pipe shape: Round
• External tube size: Ø50mm
• Tube wall thickness: 1-2mm
• Suggested internal fit: 46-48mm approx. (different factors affect this, including coatings, weld lines and tolerance)
• Material: Low-Density Polyethylene (LDPE)
• Fitting type: Push-fit ribbed insert

Suitable for:

• Angled legs on office and workshop furniture
• Foot bungs for chairs and tables
• Plastic stoppers for Round hollow tubes and pipes
• Feet for display systems
• Post caps for gates and railings
• Tube end caps for light fabrication projects
• Protective tube ends for finishing
• Ribbed knock-in inserts for POS and shopfitting

Tube inserts are always listed the same way that tube is listed because the head of the insert needs to marry up with the outside edges of the tube.  They often come in a variety of wall thicknesses and gauge sizes but if you're unsure on fit, you can click the 'Request Sample' button, or for help measuring your tube, try out this useful sizing pdf.

If this isn't quite right for your application, check out our other inserts for round tube here and if you're not looking to plug the end of a piece of hollow tube and instead after a generic hole plug, then maybe one of our covers caps or panel plugs will work better for you.

Bought these to fit on end of the bed after removing the brass fitting. Look good and took seconds to fit.

Q: Hi, Could you let me know what the RAL colour reference, (or any colour ref) of the Mid grey feet is please.
