The Lindab Gutter Union (100mm) is designed for professional contractors and DIY enthusiasts who require a secure, reliable method for joining gutter sections within the Rainline system. Its primary benefit is a high-performance, watertight seal that requires no messy adhesives or specialized tools, though it is exclusively compatible with the 100mm Rainline product range. This galvanized steel component provides a rust-resistant, low-maintenance solution for both residential new builds and system refurbishments.

No, the Lindab Gutter Union features an integrated rubber seal that provides a watertight connection without additional sealants.
No, this specific model (RSK100BK) is designed exclusively for the 100mm Rainline system.
The galvanized steel and coating are engineered to resist discoloration and rust, ensuring the finish remains stable over time.
Yes, the snap-fit design allows for manual installation, though a ladder and proper safety equipment are required for roof work.
The union is specifically designed to accommodate thermal movement, allowing the gutter lengths to expand and contract without breaking the seal.
Check that the gutter ends are cut square and are not deformed. Ensure the rubber seal is seated correctly within the union channel.
Verify that the gutters are fully inserted into the union and that the locking mechanism is completely closed.
To install, ensure your 100mm Rainline gutter sections are cut cleanly and free of metal burrs. Position the union at the center of the joint and press down until the snap-fit mechanism locks. This product is strictly compatible with the 100mm Rainline guttering system; attempting to force it onto other systems will result in a faulty seal. To maintain, simply wipe down the exterior with a damp cloth if debris accumulates during annual gutter cleaning. Inspect the rubber seal every few years during routine maintenance to ensure it remains pliable, though the high-quality material is designed to last for the duration of the system's life.
