Gargoyle downspout extension: measure the pipe first
Updated: 22 October 2026
The splash under your downpipe is a sizing problem, and a gargoyle downspout extension only helps if the mouth meets the pipe you have. In this set of six, one row is sold as that mouth, and the page does not print the opening. UK downpipes are not one size, and standard does not say which is on your wall. You should leave knowing what to measure, and when a gutter fitter is the next call. Peter F. used the Ranier listing of 19 October 2026 and UK reviews as reports, and did not fit a mouth to a pipe. Freestanding statues on the [gargoyle comparison](/hub/garden-decor/gargoyle) are a different job.

A mouth is not a garden statue
Gloucestershire Archives describes a historic gargoyle as the carving that throws water clear of a wall, and a grotesque as the face that does not. The object on a modern plastic downpipe is a resin diverter, not a spout built into the masonry. It still has to match a pipe a fitter would measure in millimetres.
In this set the water job is only Design Toscano Ranier, model CL4370. On 19 October 2026 it was about £14.56, with 4.7 from 284 ratings. The uses line says Home. It is wall-mounted polyresin, and the listing says to wipe it clean. The Chained Cathedral is freestanding and has no water job. The best garden gargoyle page can call Ranier the best value and still leave the opening unsolved. If you have not separated shelf, statue, and mouth, the garden gargoyle buying guide does that first.
The number the page leaves out
Ranier does not print a maximum opening. That is the number that decides the purchase. The bullets give about 40.5 × 20.5 × 12.5 cm and 2.25 kg. The item weight is 1.36 kg. Both stay on the record. Do not average them into a weight the listing never chose.
UK buyers have reported a square opening that missed, a pipe a buyer cut, and a 32 mm hose that fitted. Those are reports, not a method to copy. A 32 mm hose does not mean a 68 mm round pipe will seat. Reviewers also call the body hollow, and one brings it indoors. How to winter a resin body is on the resin gargoyle winter care page. The 4.7 does not say it matched a UK round pipe.
UK pipes are round, square, or something older
Brett Martin's domestic plastic systems use a 68 mm round downpipe on Roundstyle and Deepstyle, and a 65 mm square downpipe on Squarestyle and Prostyle. The same FAQ lists a cast-iron-style rectangle of 100 mm × 75 mm, plus larger rounds from 105 mm. BuildWiz notes that round and square are not interchangeable without an adaptor.
Roland the Gargoyle is not in this set. It states rectangular downspouts up to 5.75 cm × 7.5 cm. A UK review on that other listing said a 68 mm round pipe worked. That report stays on Roland. It does not transfer to Ranier. Euiroet and Teaeeno print up to 3 in × 4 in, about 76 mm × 102 mm, a US rectangular downspout rather than a 68 mm round UK pipe. Measure the end you have.
Before you cut the pipe
Measure the outside of the pipe where the mouth would sit, and write down the shape. A 68 mm round and a 65 mm square are both common, and they do not meet without an adaptor. An older rectangular pipe can be 100 mm × 75 mm. If the listing prints no maximum opening, you do not yet know whether any of those three will seat. Dry-fit only if you can do it without cutting.
If water is already in the wall, a resin mouth is not the repair. Ask a gutter fitter where the leak starts. Screw nothing into a listed wall until the planning authority has said the fixing is acceptable. If the opening in your hand misses the pipe, the return is the remedy. Once a hollow mouth does fit, water sitting inside can still freeze.
Common questions
What opening does Ranier fit?
The listing does not say. Design Toscano Ranier, CL4370, gives a title height around 41 cm, bullets of about 40.5 × 20.5 × 12.5 cm and 2.25 kg, and an item weight of 1.36 kg. It prints no maximum opening. UK reviews mention a square opening that missed, a pipe a buyer cut, and a 32 mm hose that fitted. Those are reports, not a size to order against. Measure your pipe.
What are the usual UK domestic downpipe sizes, and why is standard not enough?
Brett Martin's domestic ranges use 68 mm round and 65 mm square downpipe, depending on the profile. The same maker lists 100 mm × 75 mm rectangular in a cast-iron style, and larger rounds from 105 mm upward. Round and square need an adaptor to meet. Standard downspout does not say which of those is on your house. A gargoyle page that prints neither size is not being specific.
Is a listing that says 3 in × 4 in, or 5.75 cm × 7.5 cm, describing my round pipe?
It is describing a rectangle. Roland, outside this set, prints rectangular downspouts up to 5.75 cm × 7.5 cm. Other cards print up to 3 in × 4 in, about 76 mm × 102 mm, a US section. Your pipe may be 68 mm round or 65 mm square. One Roland reviewer with a 68 mm round pipe said his pipe worked. That report stays on Roland's page. It is not a fit claim for Ranier.
What do I measure on the pipe before I order?
Measure the outside at the end the mouth would cover, and note round, square, or rectangular. Write 68 mm round and 65 mm square as different answers. If you have an older metal rectangle, measure both sides, because 100 mm × 75 mm is a size Brett Martin still lists. Compare those numbers with a printed maximum opening. If the gargoyle page has no maximum, you do not have a match yet.
If water is already in the wall, is a resin mouth the repair?
A mouth at the bottom only throws water that still reaches it. If the wall is already wet, the leak may be a joint or a blockage higher up, and a gutter fitter should see that. A polyresin diverter does not dry masonry and does not replace a failed length of pipe. Fit a mouth when the pipe is sound and the remaining problem is splash at the outlet. The Chained Cathedral will not do this job. It is a freestanding statue, not a diverter.
