The Lindab Steel Corner Overflow Protector (OSKBK) is an essential component for homeowners and contractors looking to manage high-volume rainwater flow at 90-degree internal gutter angles. Designed as part of the premium Lindab Rainline steel rainwater system, this protector effectively prevents water spillage during heavy downpours, protecting building foundations and facades. While it is engineered for exceptional durability and ease of use, it is specifically designed for integration with Lindab's own gutter profiles, meaning it may not fit non-standard or third-party guttering systems.

Check that the protector is fully seated and clicked into place; verify that the gutter is free of blockages preventing downward flow.
Ensure you are using the correct diameter guttering (100-190mm) and that the gutter ends are cut square.
Installation of the OSKBK is straightforward due to the Lindab push-fit system. Ensure that the gutter sections meeting at the 90-degree corner are cleanly cut and free from debris. Align the protector with the corner joint and press firmly until it snaps into the locked position. No sealants are required as the system is designed for a precision mechanical fit. For maintenance, simply clear leaves or moss accumulation from the guttering annually; the galvanised steel is rust-resistant and does not require painting or specialized treatments to maintain its performance over its 70-year lifespan.
