Join 140 mm rectangular steel gutter runs quickly and cleanly with the Lindab Magestic Galvanised Rectangular Gutter Joint with Rubber Seal (RTSK140MG). Engineered for rapid installation, the click-and-lock mechanism creates a neat, secure connection between straight lengths or angles, while the factory-fitted EPDM gasket delivers a watertight, sealant-free joint—no screws required. Formed in Lindab’s Magestic galvanised steel, the zinc–magnesium enhancement stabilises the coating and protects zinc’s naturally porous structure for outstanding corrosion resistance, including in exposed and coastal locations. The unpainted finish settles to an elegant dark-grey patina over time and coordinates perfectly with Lindab rectangular gutters, outlets and downpipes. Ideal for both new builds and refurbishments, this durable, recyclable joint helps installers achieve crisp lines, reliable flow and low maintenance across long elevations.
