Adjustable Leveling Feet for 40mm Tubes

These adjustable leveling feet fit into 40mm square tubes to stabilise office or household furniture on uneven floors. The set includes eight inserts with threaded screws that raise the item height and reduce ground contact area. A plastic base prevents floor scratches on hardwood, tile, linoleum and vinyl plank while blocking moisture and rust rings. They suit desks, sofas, cabinets or light industrial machines with threaded sockets.

Simple Press-Fit Installation

Each insert presses into the open end of a 40mm square tube; no tools are required beyond hand-tightening the screw to the desired height. The plastic base stays fixed while the threaded stem turns, so the floor surface never drags. Common issues arise when the tube interior diameter differs from the nominal size, causing a loose or tight fit, or when the existing leg lacks a threaded socket for the stem to engage.

Verify Tube Dimensions Before Ordering

Confirm your furniture legs are square tubes with a 40mm external dimension and an open end that accepts the insert. Check that the leg interior is clear of welds, caps or cross-braces that would block insertion. Ensure the leg material can accept a threaded stem or that a threaded socket is already present. These feet are not suited for round tubes, solid legs or profiles larger or smaller than the stated size.

What components are included in the 8 sets and is any extra hardware required?

Each set contains an adjustable leveling foot and a 40 x 40 mm square tube insert; no additional hardware is mentioned, so the feet install directly into threaded sockets on your furniture or equipment.

Which version should I choose for 40 mm square tubing?
