## Questions & Answers

**Q: Is the lid flat on each side please?  I just need the lid but can't see from the picture if the 'tube' bit is just attached to the frame?  Thanks**
A: The lid is flush with the frame- the tube bit is molded to the square frame - I didn’t want the tube so I hacksawed it to an acceptable depth for my requirement!

**Q: What tool do you use to remove them. Doesn’t look like a screwdriver or Allen key?**
A: Phillips screw driver

**Q: Hello - is the frame 320x320 and the lid 300x300?**
A: Yes that’s correct

**Q: Does anyone know where I can buy just the cover? I need about 4 of them but don’t want the whole unit?**
A: You want a poly pipe UG502. There are two different types though old style has been discontinued. Call polypipe direction

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great - replaced Polypipe lid
*by G***S on 3 November 2023*

I bought this for the lid only to replace a Polypipe lid that failed.The product fits perfectly and installed easily into the existing orifice. There is a slight misalignment of the holes, maybe 1mm, but as the original screws were in a state and the new supplied screws are self tappers they can be made to fit by careful angling of the installation. The whole thing and screws install totally flush.The frame that would be set in the ground is surplus to requirement but appears to be solid.Would recommend.

### ⭐⭐⭐⭐⭐ Fantastic value for  money
*by S***E on 10 April 2021*

Been looking on the internet and couldn't find the right size, then came on here and it was the first one that came up. It came within a couple of days and is fantastic value for money. I only needed the lid to start with but the screws for the old one were seized in, so I decided to remove and replace the lot. It only took two minutes to dig the old one out and drop the new one in and it was a perfect fit. I have even ordered a spare one incase I am stupid enough to go over it again with the mower 😂

### ⭐⭐⭐⭐ Sturdy and well made
*by G***S on 29 April 2025*

Slightly loose fit, but good product, very sturdy and a good price
