About this asset

The Lindab RSK 125 is a 3D Revit family component designed for secure, watertight connections in semi-circular rainwater gutter systems. This gutter joint features a robust semi-circular profile engineered for seamless integration with standard 125mm guttering systems. The assembly consists of a durable steel exterior housing that provides structural rigidity and a ribbed black rubber gasket liner, which ensures a compression-tight seal at the junction. The design includes integrated metal tabs and fastening points for mechanical installation. Its precision-moulded geometry allows for rapid alignment during assembly, ensuring that the joint maintains the necessary slope for efficient water runoff. The finish is consistent with standard galvanised or coated steel rainwater components.

The download is a 522 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

As a native Revit family, this component is designed for placement within a roof drainage assembly. Users should load the RFA file into their project environment and snap the joint to the gutter edges using standard alignment tools. The component is typically hosted as a standalone fitting within a larger drainage run. Ensure that the project template includes the correct material parameters to reflect the intended finish for visual schedules and high-fidelity project documentation.

This gutter fitting is essential for residential and small-scale industrial roofing projects where professional-grade drainage systems are required. It is commonly specified by architects and MEP engineers during the design development phase to ensure accurate material take-offs and clash detection in BIM models. Professionals searching for this component often look for rainwater system accessories, gutter couplings, or roof drainage fittings to complete their site plans. It pairs effectively with standard steel downpipe and gutter segments in external building envelope modelling.
