Snap-In Square Plugs


Style 1	Style 2

Press firmly into square holes for a tighter hold than push-in plugs. These are good for semi-permanent installations, such as finishing the ends of posts and furniture. To remove, you’ll need a tool such as a flat-head screwdriver to pop them out.

Styles 1 and 2—Flexible ribs compress and expand to secure the plug.

Polyethylene—A balance of wear and chemical resistance for use in a variety of environments. These plugs withstand scratches and scrapes as well as mild acids, solvents, and chemical cleaners.

Vinyl Plastic—More durable against wear and tear than polyethylene. These plugs also hold up to oils, mild acids, and solvents.
