Upgrading your guttering shouldn’t mean replacing everything. The FloPlast Half Round To Cast Iron Half Round Gutter Adaptor - Black helps you join modern plastic guttering to traditional cast iron systems—quickly and securely.

FloPlast created this adaptor to solve a common headache: mixing old and new gutter systems. With its clip-fit design, you can connect 112mm plastic half round guttering to your 4" cast iron gutter without hassle. You won’t need special tools or sealants. Just push it in place and seal the gap with a small amount of silicone for extra protection.

Made from durable black uPVC, this adaptor resists cracking, fading, and UV damage. It blends cleanly with both cast iron and plastic systems, giving your roofline a tidy, professional finish. Whether you’re restoring a heritage property or extending a newer one, this adaptor helps you save time, money, and effort.

Installers and homeowners across the UK trust FloPlast for reliable, long-lasting gutter fittings. This simple adaptor delivers peace of mind—without the mess.
