Leveling Mount Inserts for Tubular Legs

Slip these inserts into tubular legs to quickly add threads for attaching leveling mounts. They’re often used in the legs of light equipment and furniture.

Square inserts have flexible spring steel walls that grip the inside of the legs.

Retaining clips hold the round inserts inside the legs.
