Control splash and keep water inside the gutter on long, high-flow runs with the Lindab Magestic Galvanised Straight Overflow Protector — OSKR, 125 mm. This discreet clip-on deflector raises the working edge along straight sections, reducing spillover during cloudbursts or where multiple roof areas converge. It’s a fast, tool-free retrofit that simply hooks over the gutter’s rolled bead, making it ideal for upgrading existing installations as well as new builds. Formed from Lindab’s Magestic galvanised steel, the zinc–magnesium enhancement stabilises the coating and protects zinc’s naturally porous structure for excellent resistance to red rust and white staining—even on exposed or coastal sites. Supplied unpainted, it will weather to a refined dark-grey patina that complements both heritage brickwork and contemporary cladding. Use OSKR on straight runs and pair with the OSK corner protector where surge points occur at external or internal angles for a cohesive, high-performance rainwater system.
