Threshold Drain – Black Aluminium – Outdoor Drainage Solutions

Product Overview

This 1m low-profile surface water drainage channel is designed for threshold and entrance applications. Combining a slim 60mm x 100mm plastic channel body with a high-quality black aluminium grating, it provides discreet yet effective protection against rainwater ingress at doorways, patios, and paved entrances.

Manufactured from tough, lightweight polypropylene, the channel casing offers strength, stability, and resistance to corrosion. The black aluminium grating delivers a durable and modern finish that integrates neatly with contemporary paving and door profiles. Its compact dimensions make it ideal for installations where space or ground depth is limited. The narrow cross-section allows the system to sit flush against door thresholds, collecting surface water efficiently while maintaining a clean and unobtrusive appearance.
