Flexible length and continuously adjustable height.
The patented system for standard-compliant interconnecting doorways without the need for special design.

AquaDrain® Flex drain grates guide surface water directly into the attached drainage. This helps solve connection problems even for low door / wall connections. Thanks to the adjustable sliding feet, AquaDrain® Flex drain grates can be cut to the required individual length on site.

Advantages of AquaDrain® Flex

  • Cutting to length saves time and cost: simple and versatile, directly on site.
    Thanks to two adjustable sliding feet and patented frame geometry, time-consuming and expensive custom sizes are no longer required. The feet also serve as connectors to link one grate to another.
  • Integral dirt trap protects against fouling.
    The trap prevents dirt falling into the drain grate, guaranteeing  permanent drainage performance by grate and surface drainage .
  • Simple, precise adjustment to the covering height due to screw feet that can be adjusted from above.
  • Maximum drainage performance due to drain grate open below combined in a system with AquaDrain® surface drainage.
    Guarantees maximum drainage capacity without accumulation of water. Drainage of façade and surface water is carried out  unimpeded and safely underneath the covering.
  • Allows for practical and standard-compliant reduction of door threshold heights from 15 to 5 cm.
