Description
Competa CUG4RTSA Round to Square Adaptor for Bottle Gullies
The
Competa CUG4RTSA round to square adaptor is a black accessory designed to convert the round top of a compatible bottle gully into a square-format drainage opening. This
180mm bottle gully adaptor provides a practical solution where a square top is preferred for fitting neatly alongside paving, slabs or other straight-edged finished surfaces. The
bottle gully round to square accessory allows a compatible round bottle gully to be adapted without replacing the complete gully body. As a
round to square gully adaptor, it is particularly useful during new paving work, alterations and drainage repairs, providing a straightforward
underground drainage gully adaptor for compatible installations.
Competa CUG4RTSA Round to Square Adaptor
The
Competa CUG4RTSA round to square adaptor is designed to sit on the upper section of a compatible bottle gully and provide a square-format top. This can be especially useful where the surrounding finished surface is being formed with paving slabs, block paving or concrete and a square drainage opening gives a neater finish than the original round gully top.
180mm Bottle Gully Adaptor
The
180mm bottle gully adaptor is intended for compatible bottle gullies using the approximately 180mm round upper section stocked within this drainage range. Before ordering, check the dimensions of the existing gully. Bottle gully sizes and locating features can vary between manufacturers even where the connected underground pipework is nominally 110mm.
Bottle Gully Round to Square
The
bottle gully round to square design provides a simple way to change the appearance and shape of the gully opening while retaining the compatible bottle gully body underneath. This can avoid replacing an otherwise serviceable gully simply because a square surface finish is required at paving level.
Round to Square Gully Adaptor
A
round to square gully adaptor is particularly useful when finishing drainage around square or rectangular paving because the adaptor can be easier to integrate neatly with straight paving cuts. The surrounding paving should remain correctly supported and should not place unnecessary load directly onto the adaptor or bottle gully body.
Underground Drainage Gully Adaptor
This
underground drainage gully adaptor forms part of the upper section of a compatible external drainage installation. It does not replace the bottle gully trap or underground drainage connection beneath it. The existing gully should be correctly installed, supported and in serviceable condition before adding the adaptor.

Why Convert a Round Bottle Gully to Square?
A square gully opening can make it easier to achieve a neat finish when the surrounding area is being paved using square or rectangular materials. Rather than cutting complex curves around a round gully top, the square format can allow straighter paving cuts and a more uniform appearance around the drainage point.
Typical Applications
The CUG4RTSA adaptor can be useful in suitable external drainage locations including:
- Patios
- Block paving
- Garden paving
- Paths
- Yards
- Domestic drainage points
- Existing bottle gully upgrades
- Extension and renovation projects
- Replacement and repair work
Checking Bottle Gully Compatibility
Before fitting the
180mm bottle gully adaptor, measure the upper section of the existing bottle gully and check that its shape and locating features match the adaptor. Do not assume that every nominal 110mm bottle gully uses the same top dimensions. The 110mm measurement usually relates to the connected underground drainage pipework rather than the diameter of the gully opening.
Fitting the Round to Square Gully Adaptor
Remove the existing grid or top component as required and clean loose dirt, soil and debris from the upper section of the bottle gully. Position the
round to square gully adaptor correctly over the compatible gully and check that it sits evenly and securely before completing the surrounding paving. Maintain access to the drainage opening so that the bottle gully can still be inspected and cleaned when required.
Using the Adaptor with Paving
When the
bottle gully round to square adaptor is being installed within paving, establish the final surface level before permanently finishing the surrounding area. The paving should fall appropriately towards the drainage point where surface water collection is required, while the adaptor should remain level and accessible.
Bottle Gully Accessories
The CUG4RTSA can be used alongside compatible bottle gully components within the Competa drainage range, including standard and back inlet bottle gullies, riser extensions and replacement grids. If the existing gully needs additional height before reaching the finished surface, check whether a compatible bottle gully raising piece is also required.
