The Freeflow 65mm Square To Round Downpipe Adaptor is a high quality, practical and essential rainwater system accessory for transitioning between square and round rainwater downpipes in your Freeflow Rainwater System. Designed to connect 65mm square downpipe to 68mm round downpipe, this adaptor allows flexibility within a rainwater installation where differing pipe profiles are required, without compromising performance or appearance.
Manufactured to integrate seamlessly with the Freeflow rainwater system, the FRS531 adaptor is ideal for both new installations and refurbishment projects. It is particularly useful where an existing round downpipe run needs to be connected to a square system at gutter level, or where pipe profiles change further down the building.
Made from high-quality, low-maintenance uPVC, offering excellent resistance to weathering, warping, UV exposure and impact. It will not rot, flake, rust or corrode, ensuring long-lasting durability and a secure, watertight connection. Lightweight and easy to install, it slots neatly into compatible Freeflow downpipes and fittings for a smart, tidy and professional finish.
Please note, once the order has been delivered you must unwrap the product and ensure that the products, including fittings, are stored out of the sun until fitting.
