30 mm Square Tube Leveling Inserts

These inserts fit 30 mm square tubing on office or household furniture and light industrial machines with threaded sockets. They provide adjustable height and stability for items that wobble on uneven floors. The plastic base prevents floor damage and eliminates noise during use. Four complete sets are included for multiple legs.

Sustained Load Behaviour

The adjustable screw allows fine tuning so each leg carries its share of the load continuously without shifting. The plastic base distributes pressure evenly across hardwood, ceramic tile, vinyl plank or linoleum surfaces. No rust rings form even when the furniture rests on damp floors for long periods. Friction is reduced so the piece moves smoothly when repositioned.

Build Quality and Mounting Implications

Each foot combines a metal threaded insert with a durable plastic base that resists cracking under static weight. The insert slides into the square tube and secures with the supplied nuts for a firm mechanical joint. No adhesives or special tools are required for installation. The design suits indoor furniture and light machinery where floor protection and quiet operation are priorities.
