Control splash on long, high-flow runs with the Lindab Magestic Galvanised Straight Overflow Protector — OSKR, 150 mm. This discreet clip-on deflector raises the effective front edge along straight sections to reduce spillover during cloudbursts or where multiple roof areas converge. It’s a quick, tool-free retrofit that hooks over the rolled bead, making it ideal for upgrading existing installations as well as new builds. Manufactured from Lindab’s Magestic galvanised steel, the zinc–magnesium enhancement stabilises the coating and protects zinc’s naturally porous structure for excellent corrosion resistance—even on exposed or coastal sites. Supplied unpainted, it weathers to a refined dark-grey patina that complements brick, render and modern cladding. Complete your system with matching Magestic gutters, brackets and downpipes; for colour-matching, coordinating Rainline painted components are available in 12 colours.
