Universal decking spacer with four thickness settings — designed for accurate, durable outdoor decking installations Key benefits Precise gap control: Four discrete thickness options let you set consistent joint widths in four steps. The universal spacer provides repeatable alignment for professional-looking, evenly spaced joints with all composite materials. Weather-resistant performance: Engineered material design resists weathering and UV exposure, delivering reliable performance in rain, snow, and sun. Suitable for long-term outdoor use with treated timber and composite boards. Improved drainage and ventilation: Integrated water‑drainage feature and enhanced ventilation support moisture runoff and air circulation beneath boards, stabilizing decking during installation and reducing the risk of trapped water. Wide compatibility: Made for universal use with WPC decking and other composite or timber surfaces. Ensures consistent joint sizes at pool edges, terraces, and walkways to maintain a uniform appearance and structural integrity over time. Function and compatibility Function: Acts as a spacer and temporary support during installation to maintain even gaps, align boards, and improve installation speed and accuracy. Compatibility: Compatible with WPC (wood-plastic composite), treated wood, and most decking systems that require fixed joint spacing. Material and performance: Constructed from a purpose-designed, weather-resistant material that minimizes erosion and degradation from outdoor conditions while preserving mechanical stability during mounting. Typical applications Pool surrounds: Keeps a consistent gap at pool edges to handle moisture exposure and to maintain a neat, safe perimeter. Terrace and patio decking: Ensures even joint spacing across large deck areas for a uniform look and stable surface. Garden paths and walkways: Stabilizes boards during installation to produce straight runs and consistent gaps on paths and steps. What it solves Eliminates uneven gaps and guesswork during board laying. Reduces water retention under boards by improving drainage and airflow. Extends the useful life of outdoor decking installations by using weather-stable components during assembly. Technical notes Four-step gap adjustment for precise control of joint width. Designed for outdoor installation with treated timber and composite decking systems. Use as temporary spacers during fitting, fastening, and final alignment to achieve consistent, professional results.
