30x30mm Square Ribbed Tube Insert, 2-3mm

These 30x30mm square ribbed tube inserts are designed to provide a clean, secure finish for square tube and box section. Thanks to the flexible lateral ribs running around the shank of the insert, they should be suitable for tube wall thickness of between 2 to 3mm metric (10-14 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 box section, sitting flush with the outside edges of the tube, providing a neat finished appearance.

Key Features:

• Fits hollow tube or box section with a 15x15mm 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

Technical Information:

• Tube or box section profile: Square
• External tube size: 30x30mm
• Tube wall thickness: 2-3mm
• Suggested internal fit: 24x24mm to 26x26mm approx. (different factors affect this, including coatings, weld lines and tolerance)
• Material: Low-Density Polyethylene (LDPE)
• Fitting type: Push-fit ribbed insert

Suitable for:

• End Stops for Office and Workshop furniture
• Foot Bungs for Chairs and Tables
• Plastic Stoppers for square hollow tubes and box section
• 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, if for instance you want inserts or feet for an angled chair leg or just simply prefer something with a more enhanced cosmetic head than a bog standard flat insert, then take a look at our range of domed, angled or pyramid head inserts.  We've also got All-Metal Inserts and Square Threaded Inserts for Feet & Castors but if you're not finding what you're needing then just give us a call, drop us an email or use the livechat facility.

Unhappy that the goods were delivered to the billing address and not our premises.Hope this can be sorted for the next order.

Response from BPF Websales
Thanks for the feedback and just looking at your order confirmation, which shows the delivery address entered - I notice that you've left this in one of the fields : 'Carrowreagh Road', so that appears in both your invoice and delivery address, which obviously doesn't look right. That's what could have thrown the carrier, assuming the postcode entered of BT23 5LB was correct but obviously that's just supposition on our part. What I would say though, is cookies on your pc are likely to remember that address next time you use our website, so make sure you correct that if you can, as our systems are automated so they trust that what you've entered is correct and is how it will appear to the carriers or postie!

For once the product didn't fit at all well. The tube is within the quoted range (3mm thick) but the fins sheared off on insertion as if it was too tight. Left the product in warm water for a while but no real improvement. Did actually go in but not sure it will retain that well.
