Wavin Osma Squareline Stopend External White - 4T811W

The Squareline Stopend is used to close off the end of the 100mm Squareline gutter, preventing water from escaping and ensuring it is directed towards the downpipe.

No, this stopend is specifically designed for the Wavin Osma 100mm Squareline gutter system and is not guaranteed to be compatible with other brands or profiles.

The Flexiclip seal jointing mechanism is designed for a watertight connection. Ensure the stopend is pushed on firmly until the clip engages properly. Regular checks and maintenance can help maintain the seal's integrity.

The stopend comes in a white finish. While painting is possible, it is recommended to use a paint suitable for uPVC and to follow manufacturer guidelines to ensure adhesion and durability, as painting may affect the warranty or appearance.

An external stopend fits over the outside of the gutter end, while an internal stopend fits inside the gutter end. This model (4T811W) is an external stopend.

It is recommended to check your guttering system at least twice a year, typically in spring and autumn, to clear debris and ensure all connections are secure.

Ensure the gutter end and the inside of the stopend are clean and free of obstructions. A light application of silicone lubricant may help. Verify you are using the correct stopend for the 100mm Squareline gutter.

The stopend may not be fully engaged. Gently try to disengage and re-attach the stopend, ensuring the Flexiclip mechanism clicks into place. Check the seal for damage and replace if necessary.

Re-seat the stopend, ensuring it is pushed on fully until the locking mechanism is engaged. If the gutter itself is damaged at the end, it may need to be trimmed slightly or replaced.
