WiseGuides® Deck Board Gap Spacer Tools

Decking Board Gap Spacing Jig


DeckWise® spacers make a great addition to your deck building toolbox.

The versatile design allows you to use these spacers in any position between deck boards. The color-coded design makes finding the right spacer easier than other generic, disposable brands on the market. The blade design prevents denting or marring of decking boards when the boards are pressed together. The unique handle makes moving laterally in between boards a smart choice!
