The Lindab Magestic Conical Downpipe Bend is an essential component for professional installers and homeowners looking to create custom offsets or swan-necks in steel rainwater systems. By offering a precise 70-degree redirection, this fitting ensures seamless integration within your downpipe layout, providing superior longevity through its magnesium-zinc alloy construction. While it delivers industry-leading corrosion resistance and a unique self-healing finish, users should note that the metallic aesthetic will naturally weather and darken to a deep grey over a period of 3 to 5 years rather than remaining bright silver.

No, this component is designed specifically for Lindab steel rainwater systems and will not provide a watertight seal with plastic pipes.
No, the magnesium-zinc alloy is self-healing and designed to be left raw to develop its natural dark grey protective patina.
This bend is designed to fit standard 87mm diameter steel downpipes.
The finish typically shifts to a dark grey metallic appearance over 3 to 5 years, depending on local environmental conditions.
Yes, you can cut the component to fit, and the magnesium properties will prevent red rust from forming on the cut edge.
Ensure the pipe ends are perfectly round and free of burrs or deformation caused by cutting tools.
Verify that you are using genuine Lindab 87mm components; mix-matching brands can lead to poor fitment.
To install, simply push the male end of the bend into the female socket of your 87mm downpipe. The conical design facilitates a secure friction fit, though stainless steel rivets may be used for added security in high-wind areas. This product is strictly compatible with the Lindab 87mm steel rainwater system range. For care, avoid using abrasive cleaners that might strip the zinc layer. If the piece is cut on-site, there is no need to paint the edges, as the magnesium alloy will naturally migrate to seal the exposed steel against rust.
