Adjustable board gap spacers (set of four) Maintain consistent plank gaps across the entire deck or floor Precision edges let you set and hold uniform spacing between boards so the finished surface looks straight and professional. Use the spacer to remove guesswork and speed up layout checks. Stable, slip-resistant contact for safer work An anti-slip surface provides a secure grip on boards and helps prevent movement on uneven or sloped surfaces. That extra control reduces fumbling and rework during installation. Four identical spacers for team work and fast changes The included set of four allows multiple installers to work at once or lets you leave different spacers in place for quick switching between gap sizes on larger jobs. Keep productivity high with fewer interruptions. Simple to use for homeowners and professionals Designed to be intuitive for a weekend DIYer while being reliable enough for contractors. The tool gives clear spacing and measurement guidance across a wide variety of installation tasks. Function and compatibility Intended for use with plank-style decking and flooring installations where consistent gaps are required. Use the spacers for exterior decks, interior plank floors, stair treads, and other board-by-board assemblies. Performance benefits Reduces alignment errors and rework, speeds up layout and installation, and helps achieve a consistent visual result across long runs of boards. Practical use scenarios Building a backyard deck: multiple crew members use the four spacers to hold consistent gaps while fastening each board, keeping the deck lines straight and saving time. Installing interior wood or composite flooring: use the spacer to maintain even expansion gaps and a neat, uniform appearance across the room. Replacing or repairing stair treads and risers: the anti-slip contact helps keep pieces steady on angled surfaces while you align and secure each board. What you get Four identical adjustable board gap spacers that provide repeatable spacing and a slip-resistant contact surface for better control during installation.
