Achieve perfect levelling and enhance stability with Keay Vital Parts' German-made height adjustable square tube inserts. Designed with an innovative 2-part mechanism, these premium levelling feet offer ultimate flexibility to precisely adjust the height of your square tube furniture or equipment.


 

Precision Engineering & Robust Design

Each adjustable insert features a female-threaded part for secure fitting into your square tube, complemented by a male-threaded part that screws in to customise height. Crafted from high-quality Polyamide plastic, the one-piece outer body with an injected thread ensures superior strength and reliability for a wide range of applications.


 

Impressive Load-Bearing Capacity

These durable square tube end caps are built to support significant static loads:

- 100kg for 20x20mm and 22x22mm tubes.

- 150kg for 25x25mm tubes.

- Up to 300kg for 30x30mm, 35x35mm, 40x40mm, 45x45mm, and 50x50mm square tubes.

Please note: These inserts are engineered for static loads only and are not suitable for dynamic loads or as gliders.


 

Easy Measurement & Installation Guide

To ensure the correct fit, measure the OUTER dimensions of your square tube. For example, a 30x30mm tube with a wall thickness between 1.5mm and 2mm will fit a 30x30mm insert. These inserts are specifically designed for tubes with a wall thickness of 1.5mm to 2mm.

For detailed visual guides and to ensure the perfect size, please refer to the listing photos for each size.

Upgrade your fittings with the precision and quality craftsmanship of German engineering. Trust Keay Vital Parts for unmatched versatility and performance in your furniture, machinery, and other applications.

 

 

Product Guidance & Terms of Use

Fitting & Ongoing Maintenance: Components containing mechanical fixings should be installed using appropriate hand tools and pre-drilled pilot holes to preserve furniture structure. Glides, ferrules, inserts, and feet are consumable wear items designed to absorb friction over time. To ensure continuous protection, users are responsible for periodic inspections, ensuring fixings remain securely seated, removing trapped debris, and replacing components when the wear threshold is reached. Keep small parts away from children and pets.

Limitation of Liability: Keay Vital Parts accepts no liability for secondary damages, including substrate/floor marking, furniture wear or alterations, or physical handling incidents resulting from product wear-through, incorrect sizing, improper installation, overloading, or lack of periodic maintenance. Determining product suitability for specific flooring and furniture substrates rests solely with the end-user.
