The Black Plastic Gully Grid (150 x 150mm) is a durable, lightweight surface drainage accessory engineered to fit standard square gully traps and yard drains around domestic and commercial properties. Measuring 150mm by 150mm, this square grid acts as an efficient first line of defense, intercepting leaves, twigs, and larger debris to prevent them from entering and clogging sub-surface pipework.
 
Manufactured from high-grade, UV-stabilized black polymer, this grid is built to withstand regular pedestrian foot traffic, weathering, and continuous exposure to sunlight without cracking, fading, or losing structural integrity. The carefully spaced slotted pattern ensures rapid hydraulic water flow into the gully trap below while maintaining a safe, low-profile finish that sits flush with surrounding paving, concrete, or gravel surfaces.
 
Designed for quick, hassle-free installation and maintenance, the grid easily drops into place for simple lifting during routine drain cleaning. Whether you are finishing a patio drainage run, a pathway edge, or a building perimeter, this trade-quality plastic gully grid delivers reliable, low-maintenance performance and a neat, professional appearance.
