Square tube insert kit for furniture legs

This kit supplies ten adjustable leveling feet that fit inside 20 mm square tubing. The plastic base has a 19 mm usable connector and an M8 thread with 27 mm of engagement. It is intended for office desks, cabinets, shelving, fitness gear and similar household or light industrial items that need a stable, floor-friendly foot.

Floor protection and quiet operation

Each foot adjusts from 17 mm to 33 mm in height so the item sits level on uneven surfaces. The plastic base prevents scratches on hardwood, ceramic tile and vinyl plank flooring. It also stops rust rings on damp floors and eliminates sharp noise when the furniture is moved.

Sustained load stability

Under continuous weight the threaded insert holds its set height without slipping. The 30 mm diameter base spreads the load to reduce pressure on the floor. Height remains fixed during daily use, keeping desks, racks or equipment steady over time.

Questions about this item

How do I install these 20mm square inserts into my furniture legs?

Push each 20 x 20mm square connector into a 19 x 19mm tube end, then thread the M8 x 1.25 stud 27mm into the leg socket; the step people miss is checking that the tube inner dimension matches the 19mm usable size before forcing the insert.

What maintenance or replacement will these leveling feet need over time?

The plastic bases can wear or crack on abrasive floors, so inspect them periodically and replace any foot that no longer glides smoothly or shows visible damage; the M8 threaded studs themselves do not require lubrication.

What is the first limit I will hit when levelling heavy equipment on these feet?

The adjustable height range stops at 33mm, so any floor slope or leg-length difference greater than that cannot be compensated without shims or longer studs.
