Flexible spacer system for outdoor decking — precise, durable, easy to use Key benefits — why you need it Ensures millimeter-accurate board alignment with four adjustable height settings, so gaps and board runs stay consistent across the whole deck. Reduces installation time and complexity by providing a reliable, repeatable spacer that simplifies laying, clamping and fastening. Weatherproof, erosion-resistant surface maintains fit and performance in all climates — designed to work with pressure‑treated (kesseldruckimprägniert) wood and compatible with composite decking. What makes it stand out Four precise adjustment stages: set exact board spacing and height quickly for uniform results across different board thicknesses. Durable, weather-resistant construction preserves alignment over time and limits maintenance needs. Designed to promote drainage and airflow beneath boards, improving stability and reducing moisture-related problems. Features and performance Adjustable spacer with four predefined positions for millimeter-accurate alignment. Erosion-resistant surface for long-term dimensional stability in outdoor conditions. Optimized geometry for drainage promotion and stabilization during installation and in finished decking. Suitable for use with pressure-treated wood and composite materials; supports consistent clamping and spacing during fastening. Practical applications (examples) Poolside decking: maintain even gaps and promote drainage to avoid standing water and reduce slip risk when using composite boards or treated timber. Terrace and patio installations: simplify board alignment and clamping for a fast, repeatable workflow on large surfaces. Garden paths and walkways: create consistent spacing and stabilized boards on uneven substrates while ensuring airflow to reduce trapped moisture. What installers can expect Faster, more predictable installations with fewer adjustments on site. Consistent gap control for aesthetic and functional results. Compatibility with common outdoor decking materials without special tools. Composition and compatibility Weather-resistant spacer system with an erosion-resistant surface finish. Designed specifically for outdoor decking projects and compatible with pressure-treated wood and composite decking materials. Includes Adjustable spacer elements with four precise positions for reliable, repeatable board spacing and alignment.
