3/8" IPE Plugs are straight sided wood plugs that fit 3/8" holes on Ipe wood decking, Ipe stairs, boat decks, outdoor furniture and other projects. 3/8" 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 3/8" 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. 3/8" IPE Plugs can be sanded, stained and varnished.
