DeckWise Standard Hardwood Plugs create a fastener-free deck surface. Made from real hardwood and tapered for easy installation, they can perfectly blend into the rich tones of Cumaru, Ipe, Tigerwood, or Massaranduba. These hardwood plugs are perfect for starter boards, end boards and stairs when using a clip system such as Ipe Clip Hidden Deck Fasteners. Plugs install easily in 3/8" pre-drilled and countersink holes with Gorilla Glue. All protruding plug material can simply be hand sawed or sanded off for a smooth, flush finish.
