Frequently asked questions
Measure the internal opening (length × width) of the hole you want to cover — do not measure the old frame or cover itself. For example, a 600×450 mm hole requires a 600×450 mm cover (or slightly larger). If in doubt, send photos and measurements of the hole you need to cover and we’ll confirm.

You need to select the best cover based on:
- Load rating (pedestrian, driveway, heavy vehicle)
- Location (garden, patio, driveway, road)
- Material (steel, ductile iron, aluminium)
- Size (clear opening of the chamber)
- Finish (recessed, solid top, sealed, locking)

Installation is straightforward:
- ensure the frame is level and properly supported,
- bed the frame securely in concrete,
- infill the tray with your chosen surface while keeping it flush with the surrounding area,
- allow the bedding and infill to cure fully before use.
