Plastic Square Hopper Grid

Product Description

Keep your underground drainage tidy, effective, and free of debris with the Plastic Square Hopper Grid. This grid is a spare top-cover for square hoppers in underground drainage range. It’s designed for quick replacement if your existing grid becomes damaged, clogged, worn, or simply discoloured. A small but essential component, this spare grid helps maintain surface water flow, prevent blockages, and ensure your drainage system performs reliably.

Manufactured in durable, impact-resistant polypropylene, this spare grid is part of a broader underground drainage product range known for its strength and long service life. It’s built to endure exposure to the elements, resist damage from foot traffic, and handle repeated access for cleaning.

Finishing in a glossy black colour, this grid balances function with aesthetics — it’s neutral and discrete, helping your drainage installation blend with surrounding surfaces. Installation is straightforward: remove the old grid from your square hopper, place in the spare grid, and ensure it seats properly. That’s it — no need to replace the full hopper or disturb adjacent pipework.

• Glossy black finish for a clean, finished look.

• Simple drop-in replacement — no modifications required to existing hopper top.

Benefits

• Maintain system flow: Replacing a damaged or worn grid stops debris build-up and keeps surface water entering the system freely.

• Cost-effective repair: Cheaper and quicker than buying a whole hopper when only the top grid is compromised.

• Neat & clean finish: The black grid is visually unobtrusive and works well across patios, yard-edges or paved features.
