This ACO Threshold Bottom Connector will allow easy connection between 1000mm lengths of channel drain base for a secure hold. Why install ACO Threshold Channel Drain? ACO Threshold channel drain is designed for use in domestic properties to eliminate any water from pooling at external doors. The threshold is only 60mm wide and sits flush to the door for maximum discretion, allowing water to be drained away quickly and efficiently. Whilst ACO Threshold channel drain has been built with long-life and durability in mind, a choice of built-in silver or black Heelguard grates offer aesthetic design too.
