Exposed tubing can be unattractive. Square tubing plugs can provide a nice polished finish for rough edges that are created when square tubing is cut. Having tube plugs installed will keep your furniture footing clean, so you can move them smoothly over flooring and protect hard floor surfaces from scratches and scrapes. They also make great leveling items for furniture pieces that are wobbly and unstable.

The low density polyethylene (LDPE) tube plugs available from Harman Corporation come in a variety of different sizes and can be custom manufactured, with minimums, depending on the tube gauge and tube wall thickness you're looking for.
