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!
Imus Seal SealSpacer Deck Board Spacer is a revolutionary tool designed to transform your deck installation process.

1/16", 1/8”, 3/16”, and 1/4” Spacing
SealSpacer includes four of the most common deck spacing sizes:
- Orange 1/4” spacer
- Yellow 3/16” spacer
- Green 1/8” spacer
- Blue 1/16" spacer

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.

Durable and Easy To Use
SealSpacer is built to last, with a rugged design that stands out from the competition. The Classic version features an all-in-one swivel design that flips spacers into place during use and folds them away for compact storage. The Lite version offers similar durable spacer components in a lightweight, individual format that’s simple to use and built for repeated jobsite use.

Ideal for Treated Wood and Composite Decking
SealSpacer, with its range of size options, is compatible with all decking, including composite, wet, or dry lumber.
