30 mm Square Tube Leveling Feet

These adjustable leveling feet fit inside 30 mm square tubing to stabilise chairs, tables, shelving or light industrial machines. The threaded stem lets you fine-tune height so wobbly furniture sits firm on uneven floors. Eight sets are included for multi-leg projects.

Check tube size and thread fit

Verify that your furniture or equipment uses 30 mm square tube with an open end that accepts an insert. Confirm the internal dimensions match the insert so the foot seats fully and the adjuster turns freely. No other tube profiles or thread pitches are supported by this set.

Plastic base protects floors daily

The nylon base prevents scratches on hardwood, tile, vinyl and linoleum while resisting moisture that causes rust rings. Height adjustment is tool-free once installed, letting you re-level items whenever the floor settles. The insert stays captive in the tube so feet cannot detach when moving furniture.

Questions about this item

What comes in the package and do I need to buy screws separately?

The package contains eight complete sets, each with a 30mm square tube insert and an adjustable leveling foot, so no extra fasteners are required.

How do I know which size insert fits my furniture legs?

These inserts are made for 30mm square tubing; measure the outside of your leg and choose this set only if it matches that dimension.

What does the 30mm measurement mean once the feet are installed on a table?

It means the insert slides into a 30mm square tube, giving a stable plastic base that protects floors and lets you fine-tune height with the threaded foot.
