FlowTHRU™ Threshold Drain

Hardware Finish / Colour Options

316 Stainless Steel


The FlowTHRU™ integrated threshold drainage solution is designed to offer a practical solution for applications where a flush sill threshold is required. A flush sill threshold allows internal and external floor surfaces to have the same finish level with no elevated threshold to create a trip hazard or interrupt the space. Visually a flush sill threshold allows internal and external living spaces to transition seamlessly and creates a great sense of space. From a practical perspective, a flush sill threshold allows improved accessibility and reduces the risk of trips and falls.

  • Fully Tested
  • Stainless Steel Construction
  • Heelsafe® Anti-Slip surface
  • Compatible with a full range of Vantage®, Elevate™ and ThermalHEART® Door Systems

Drainage is critical element with this type of installation, as the water performance of sliding, hinged and bi-fold door systems is impacted when a flush sill is used. The FlowTHRU™ integrated threshold drainage solution addresses these issues allowing the doors to drain into a recessed stainless steel trough and catering for water runoff from the door panels. This ensures there is no water seepage around the sill and minimises the risk of internal floor surfaces becoming wet, protecting carpet, timber and other internal floor finishes.

The trough is fitted with an architecturally styled stainless steel grate featuring ACO™ Heelsafe®Anti-Slip surface, complying with AS 4586 Slip Resistance Classification. for slip resistance.

The FlowTHRU™ Integrated threshold drainage solution has been tested to ensure performance in even the harshest of environments and is the only fully tested integrated threshold drainage solution for Vantage®, Elevate™ and ThermalHEART® door systems.

The FlowTHRU™ system is compatible with our Designer and ThermalHEART® series for single and multi-panel door systems up to 15m in length and suitable for use in residential or commercial applications. For applications greater than 15m length please contact us for a custom solution.
