Leveling Feet for 20 x 40mm Tubes

This kit supplies two sets of adjustable leveling feet designed to fit rectangular tube inserts measuring 20 by 40 millimetres. They suit office desks, household tables and light industrial machines that use threaded sockets. The plastic base prevents floor damage on hardwood, tile and vinyl surfaces while eliminating noise during use. Installation raises the item slightly to improve stability and reduce frictional resistance when moving.

20 x 40mm Rectangular Tube Compatibility

The single specification that decides fit is the 20 by 40 millimetre rectangular tube dimension. Each foot inserts directly into tubing of that exact cross-section. If the furniture or equipment uses round legs, square profiles or a different rectangular size, these inserts will not seat correctly. Buyers who need leveling feet for other tube dimensions or for bolt-on mounting without an insert should look elsewhere.

Sustained Load Behaviour

Under continuous static load the plastic base distributes weight across its surface to resist deformation and maintain floor protection. The threaded screw holds its adjusted height without creeping, keeping the item stable on uneven floors over long periods. The design reduces the contact area with the ground, so sliding effort stays low even after the furniture has remained in one position for weeks.

Questions about this item

What does the 20 x 40mm tube insert size mean for fitting my furniture legs?

The rectangular inserts fit inside legs with a 20mm by 40mm internal cavity, so measure the inside of your tube before ordering.

How does the adjustable screw thread affect levelling range on uneven floors?

The threaded stem lets you raise or lower each foot independently to compensate for uneven surfaces and stop wobble.

What floor clearance and mounting method does the plastic base require?

The plastic base sits flat on the floor and the insert pushes into the tube; no extra brackets or fasteners are needed.
