Buying guide

1. Measure the clear opening

Measure the access opening beneath the cover. Compare this with the clear opening in the product specifications, then check that there is space for the larger outer frame.

2. Check frame and installation depth

Confirm the frame can be supported around the chamber and finished level with the surrounding surface. Ask a qualified installer to check the complete assembly.

3. Choose a solid or recessed top

A solid fibreglass cover is supplied with its finished top and needs no paving infill. Natotela recessed covers take your own paving material. The recessed aluminium model lists a 285 × 285 × 50 mm tray. Have your installer confirm the usable infill thickness and construction against the actual tray. Paving inlay is not included.

4. Confirm the location

These covers are for pedestrian areas only. Do not use them in driveways, roads or parking areas. A watertight installation has not been verified for these covers; they and must not be permanently submerged.

5. Follow the installation instructions

Have the support, inlay and lifting arrangements checked against the manufacturer instructions. Keep the lifting key accessible for future maintenance.
