12mm IPE Plugs are straight sided wood plugs that fit 12mm metric holes on Ipe wood decking, Ipe stairs, boat decks, outdoor furniture and other projects. 12mm IPE Plugs have flat top, straight sides and slight camfer on bottom for easy installation. Side grain (face grain) helps repel water. All deck plugs are 10mm tall. Simply tap in with a rubber mallet or similar tool. No glue is necessary, but for wet environments a waterproof glue like an epoxy or Gorrilla glue is recommended to further improve seal. 12mm IPE Plugs can be sanded, stained and varnished. Bulk available.
