Unique-Bargains Leveling Feet 38mm Square Tube Inserts 4 Sets

Tube Insert Fit

These inserts fit 38 mm square tubing to add adjustable leveling feet to furniture or equipment. They suit office desks, household tables and light industrial machines that have threaded sockets. The plastic base protects hardwood, ceramic tile and vinyl plank floors from scratches and moisture marks. Four sets are included for a typical four-legged item.

Thread Compatibility Check

Confirm that the leg or frame has a matching internal thread before ordering. The inserts are designed for square tube profiles and will not work with round or rectangular sections. Verify the tube wall thickness allows secure insertion without splitting. No tools beyond a wrench for the adjustable screw are required for installation.

Sustained Load Behaviour

Under constant weight the plastic base distributes pressure to reduce floor indentation over time. The adjustable screw holds its set height without creeping when the load remains static. Friction between the base and floor stays low so the piece can still be repositioned with minimal effort. The design avoids metal-to-floor contact, preventing rust rings during long-term use.
