Plug Buttons

A Leading Manufacturer of Commercial and Industrial Plug Buttons


Plug buttons are a design solution for closing unavoidable holes, providing air vents, attaching glides for metal furniture, or simply adding a spot accent of color. These fasteners come in many designs and finishes for use with metal and plastic products.

Plug buttons are designed so that they may be quickly and easily snapped into place by hand. The expanding spring action of their prongs holds the fastener securely. These fasteners can then be easily removed when providing temporary closure.
