Metal Square Plugs

Designed to finish off the ends of square metal tubing, these plugs cover rough edges and block dirt and debris. Push into place and then drive with a hammer to secure.

Galvanized Steel—Strong with some rust resistance in wet environments.

Aluminum—For aluminum tubing, use these plugs instead of steel to avoid rust that spreads when different metals are in contact.
