Height Adjustable Square Tube Inserts

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.
