Imus Seal SealSpacer Deck Board Spacer is the premium, go-to spacing tool for building professionals, homeowners, and DIYers.

Spacing between deck boards is essential for effective water drainage and ventilation. Gaps that are too narrow can lead to debris buildup and inadequate airflow, whereas overly wide gaps may pose safety risks, such as difficulty walking in heels or items slipping through the decking. With SealSpacer, you can say goodbye to uneven gaps and hello to perfectly aligned decking. Some reasons many choose Imus Seal are:

  • Thousands of decks use Imus Seal products!
  • Years of experience in the deck building industry!
  • Manufactured in the USA; carefully packaged and distributed throughout North America in small batches to ensure the highest quality!

Ensure Uniformity By Matching Spacer Colors

SealSpacer’s color-coded system makes it easy to maintain consistent spacing across your entire project. Both the Classic (unique swiveling mechanism) and Lite (individual pieces) versions display the size clearly on top, with the "seal" side positioned on the bottom to space the decking. This visible sizing allows you to quickly match spacers and ensure a uniform, professional finish—no guesswork needed.

The Lite version offers similar durable spacer components in a lightweight, individual format that’s simple to use and built for repeated jobsite use.

Eagle Scout Project - SealSpacer

I just completed my Eagle Scout Project, which was to build a wash deck for The Center of Birds of Prey. I used composite deck boards that had been sitting outside for about a month while I finished collecting all the materials needed for the deck. By the time I installed the boards they were a bit warped and without the 3 Imus Seal SealSpacer deck board spacers to help provide an exact gap between boards I know the deck would not have turned out as great as it did. The spacers stayed in place as we adjusted and pushed the deck boards around and ensured a perfect gap as we fastened the boards down. Also, the ability to choose the gap width allowed me to make minor adjustments as I installed the boards to ensure a square finish on the last installed board. I cannot provide a high enough rating for this product! Small, versatile, adjustable… Valuable to the project! Thanks Imus Seal.
