What is the 300mm Round Cover & Frame used for?

Provides removable access to 300mm inspection chambers in underground drainage systems.

Which chamber systems is it compatible with?

Fits the FloPlast 300mm system including UGMBS Chamber Base and UGRS Riser Piece.

What weight rating does this cover have for vehicle traffic?

This cover is designed for domestic and light traffic applications only. It's not suitable for heavy vehicle traffic or commercial roadways.

Is this cover compatible with other manufacturers' 300mm chamber systems?

The cover is specifically designed to work with FloPlast 300mm inspection chambers, UGMBS chamber bases, and UGRS riser pieces. Compatibility with other manufacturers' systems isn't guaranteed due to different push-fit tolerances.

What's the actual external diameter of the frame for cutting concrete or tarmac?

You'll need to check the technical specifications for exact external dimensions, as the 300mm refers to the internal chamber diameter. The frame will have a larger external footprint for proper seating.

Can I adjust the height if my finished surface level isn't quite right?

Yes, you can use FloPlast UGRS riser pieces between the chamber and cover frame to adjust the final height to match your finished surface level.

How do I ensure a proper watertight seal during installation?

The push-fit system creates a watertight seal when properly seated. Ensure the chamber rim is clean and the cover frame is pushed down fully until it sits flush.

Will this polypropylene cover crack in freezing temperatures?

The tough polypropylene construction is designed to withstand normal UK weather conditions including frost. However, avoid impact when temperatures are below freezing as the material becomes more brittle.

What tools do I need to lift this cover for maintenance access?

The cover design should allow for lifting with standard drain lifting tools or keys. Check if lifting keys are included or need to be purchased separately.

Can I concrete around the frame or does it need to be left accessible?

You can concrete or mortar around the frame for a permanent installation, ensuring the frame sits level with your finished surface. The frame is designed to take this type of installation.
