About this product
DeckWise Deck Board Gap Spacers are high-visibility, impact-resistant tools designed to ensure uniform spacing between hardwood deck boards during installation. They solve the problem of inconsistent gapping caused by board variations or manual measurement errors, providing a professional finish for contractors and homeowners. These spacers are specifically engineered to sit above the joists, preventing them from falling through the gaps during the installation of dense tropical woods.

Best used for
- 1Setting consistent 1/8-inch gaps for Ipe or Cumaru decking to ensure adequate drainage and ventilation on residential decks.
- 2Achieving uniform spacing for Tigerwood or Garapa vertical fencing where visual precision is essential for the modern aesthetic.
- 3Facilitating proper expansion gaps for Red Balau or Massaranduba boards in high-moisture environments like docks or boardwalks.
- 4Aligning hardwood boards on rooftop deck systems where consistent drainage depends on precise, unobstructed gaps.
Pro tips for dense hardwoods
- For air-dried Ipe, smaller gaps like 1/8-inch are typically sufficient, but always check local humidity levels as the wood will shrink slightly as it seasons.
- When installing kiln-dried hardwoods, consider a wider spacer to allow for the natural expansion that occurs when the wood acclimates to outdoor moisture.
- Place spacers at every joist location to compensate for any slight natural bowing in dense hardwood planks and ensure a perfectly straight run.
