The Osma DeepLine Stopend is designed for homeowners and contractors installing high-capacity domestic rainwater systems who require a robust, leak-free finish at the end of their gutter runs. Its primary benefit is the combination of a high-capacity semi-elliptical profile and a pre-installed retained seal, which drastically reduces the risk of water ingress at terminal points; however, it is strictly compatible only with the Osma DeepLine 113mm range and will not fit standard half-round systems.

No, this is specifically designed for the Osma DeepLine 113mm high-capacity system and will not fit standard half-round gutters.
No, the component features a retained seal that provides a watertight fit when properly installed.
Yes, it can be removed with careful pressure, though it is designed for a permanent fit. If removed, inspect the seal for damage before reusing.
It ensures that the guttering component meets European standards for quality, size, and material durability, guaranteeing consistent performance.
Yes, the product is designed for exterior use and is formulated to resist fading and degradation from UV exposure.
Ensure the stopend is pushed fully home. Check that no debris is lodged between the gutter end and the rubber seal.
Check that the gutter end is cut square. If the gutter edge is deformed, trim it slightly and file smooth before re-attempting.
To install, ensure your gutter run is properly supported by brackets near the end where the stopend will be placed to prevent sagging. Before attaching, wipe the gutter edge clean to ensure the factory-fitted seal makes full contact with the plastic. If you have cut the gutter length yourself, file down any sharp edges to prevent damaging the internal seal. For care, perform an annual inspection of the joint to ensure debris has not built up inside the gutter run, which could create backpressure. Periodic cleaning with soapy water is sufficient; avoid using harsh solvents that may compromise the rubber seal or the UV-stabilized finish of the plastic.
