Zero Threshold Drains


Creative Drain Solutions Zero Threshold Lineal Drains are designed to provide an entirely flat, seamless connection between indoor and outdoor living and entertaining areas. The Zero Threshold Lineal Drain consist of an exterior lineal drain with a custom designed, integrated sub-sill which cradles the sliding or bi-fold door or window track to be installed. The external lineal drain acts as a water barrier between the outdoor and indoor living areas. The sub-sill cradle under the door track will then collect and direct the water or condensation on the interior or exterior of the doors or windows into the external drain.

The Zero Threshold Drain eliminates the “trip and wheel chair hazard” which has historically existed across doorways fitted with sliding or bi-fold doors. 


Custom Designed to fit proposed door frame.
