The Black Plastic Bottle Gully Circular Grid 200mm (B9171) is a durable, lightweight drainage accessory engineered to fit standard 200mm round bottle gullies used in domestic and commercial surface water systems. Designed to sit securely atop the gully head, this circular grid serves as an efficient filtration barrier, capturing leaves, twigs, and larger debris to prevent them from entering and clogging underground pipe networks.
 
Manufactured from high-grade, UV-stabilized black polymer, the grid is built to withstand prolonged exposure to direct sunlight, harsh weather conditions, and heavy pedestrian traffic without cracking, fading, or degrading over time. The precision-spaced slotted pattern maximizes hydraulic water flow into the gully trap below while maintaining a safe, low-profile barrier that prevents accidental tripping or debris accumulation at surface level.
 
Designed for quick and straightforward installation by contractors and homeowners, the grid simply drops into place or clicks securely into compatible gully bodies for hassle-free maintenance and cleaning. Whether you are finishing a domestic patio drainage run, a commercial perimeter path, or updating an existing sub-surface water setup, this trade-quality plastic gully grid delivers reliable performance, low-maintenance longevity, and a neat, professional finish.
