Description
The bottle gully round to square adaptor budget is used with compatible 110mm underground drainage bottle gullies. It helps convert a round bottle gully top into a square surface finish for paving, patios, paths and garden drainage areas.

Round to Square Adaptor for Bottle Gullies
This bottle gully round to square adaptor is used where a round bottle gully needs to finish with a square top appearance. It can help reduce awkward cutting around the gully when paving or landscaping around the drainage point.
Before fitting, make sure the bottle gully top is clean, stable and correctly positioned. Also, check that the adaptor sits flat and does not interfere with the gully grid, grate or riser.
If the adaptor does not sit correctly, do not force it into place. Instead, check the gully size and choose the correct compatible adaptor.
Bottle Gully Adaptor Installation Use
The bottle gully round to square adaptor should be fitted as part of a properly installed gully system. The gully should sit at the correct height for the finished surface level.
Good bedding, backfill and support help keep the drainage installation stable. The finished grid or grate should remain accessible for cleaning and maintenance.
This product is an adaptor only. It is not a bottle gully, trap, riser, grid or grate on its own.
Budget Adaptor for Site Drainage
This budget adaptor is useful for builders, groundworkers, landscapers and drainage installers working on smaller underground drainage jobs.
Use it on suitable patios, paths, gardens, yards and external drainage areas where a compatible bottle gully needs a square surface finish.
