18mm Round Ribbed 12° Angled Tube Insert, 1.5mm

These 18mm round ribbed tube inserts are designed to provide a clean, secure finish for hollow round tubes and legs. The head on these inserts is angled and this particular insert is pre-set at 12 degrees and would generally be used as a foot for angled chair legs.  Although our tube inserts come with a a range of angles, it's also worth considering our 'Full Dome' inserts, as the pronounced dome on these, is desigend to work with any angle.

If it's more of an angled foot you're after, then we have full domed and angled options or we also have a range of Tiltserts which may work better for you.

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're generally suitable for tube wall thickness of between 1 to 2mm metric (14-20 gauge imperial) but this particular insert foot is for a 1.5mm wall thickness. 

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.

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.
