Precision Deck Board Spacers & Leveling Jigs — keep boards evenly spaced, flat, and secure during installation. Key benefits Consistent gaps: Maintain uniform spacing for proper drainage and natural expansion, preventing water pooling and premature warping. Faster, more accurate installs: Spacers and jigs speed layout and fastening while reducing rework caused by misaligned or uneven boards. Professional finish: Helps deliver tight, straight lines and consistent surface planes for improved appearance and long-term performance. Durable for outdoor use: Designed to work with pressure-treated lumber and to withstand the demands of deck construction. What it does Deck board spacers: Create consistent gaps between boards to ensure correct drainage and allow for seasonal expansion. Leveling jigs: Adjust board height during installation to produce a flat, even surface across decking, flooring, or cabinetry. Clamp-compatible decking tool: Works with standard clamps to hold pressure-treated boards securely in position while you fasten them. Important attributes Compatibility: Built to work with pressure-treated decking and common decking materials. Also suitable for hardwood floors, cabinetry, lumber layout, and general flooring alignment. Size options: Available in four thickness options so you can choose the correct gap or shim height for your material and spacing requirements. Function & performance: Combines gap spacing, height leveling, and clamp compatibility into one set of tools to reduce setup time and improve consistency. Practical use scenarios Deck construction: Hold pressure-treated deck boards aligned and evenly spaced while you clamp and fasten, ensuring uniform airflow and water drainage. Hardwood floor installation: Use the leveling jigs to eliminate high or low boards as you lay planks, producing a flat, walkable surface before final fastening. Cabinetry and lumber layout: Speed up alignment and maintain consistent gap and height relationships across runs of boards during assembly or trim work. Quick tips Select the spacer thickness that matches your desired gap or shim requirement. Use the leveling jig to correct small height differences before final fastening. Pair with clamps to securely hold boards in place, especially with pressure-treated lumber, for safer and more accurate fastening. Reliable, multi-function spacers and jigs that simplify alignment, improve final appearance, and make deck and flooring installations faster and more consistent.
