## Questions & Answers

**Q: What is the depth (thickness) of the actual top cover**
A: The measurement from the top of the cover to the bottom of the rim that sits on the base of the frame is one inch (26 mmm). I bought mine to replace a 23 year old corroded Clarksteel 495 mm diameter cover and was lucky to find that it fitted the existing frame perfectly. It is a nice snug fit and stays firmly in place without using the securing screws which are not a feature of the original frame.

**Q: I need a 9 inch circular plastic inspection cover?**
A: B&Q
