💳 0% APR Finance Available*
Fix 150 mm half round gutters direct to the rafters with the Lindab Magestic Galvanised 210 mm Flex-Fit Rafter Bracket (K21). Built from solid 5 mm steel, this compact arm delivers confident support where fascia boards aren’t used—or whenever you want a cleaner eaves line. Flexible clips snap the gutter securely into place for a fast, tidy install, while four fixing holes provide a positive anchor into the rafter. For best performance, set brackets at ~600 mm centres and build in a 10 mm fall per 3 m to keep water moving. Need to follow a roof pitch? The K21 can be cold-formed with the Lindab KBO bracket bender for precise angle setting. Finished in Lindab’s Magestic zinc–magnesium galvanised steel, the bracket offers excellent corrosion resistance with minimal upkeep—even on exposed or coastal sites. The unpainted metal weathers to a smart dark-grey patina that complements both heritage masonry and contemporary cladding.
