Product Information
Full details
This guide is for builders, contractors, and homeowners seeking to protect wall openings from weather while maintaining airflow. The Rytons 9x9 Cowl Extra Large (ABC9TC) offers a durable, surface-mounted solution that guards against excessive weather and alleviates air blasts through cavities. Its textured roughcast finish blends with existing exteriors, though its nominal 9x9 size means the actual vent is larger to ensure adequate coverage of surrounding areas.

FAQs
What are the exact external dimensions of the 9x9 Cowl Extra Large?
The external dimensions are 274mm in length, 235mm in height, and 103mm in depth.
What is the free area of this cowl?
The free area per unit is 23,900mm² (or 239cm²), ensuring significant airflow.
Can this cowl be painted?
The product has a textured roughcast finish. While painting may be possible with appropriate exterior-grade paint, it is not specifically recommended and may affect the UV stability or textured appearance over time.
What materials are needed for installation?
You will need appropriate screws and wall fixings suitable for your specific wall material. These are not supplied with the cowl.
Is this product suitable for any 9x9 opening?
It is designed for nominal 9x9 openings and air bricks. The extra large size is intended to cover standard 9x9 openings and some minor damage or irregularities in the surrounding wall. Always measure your opening to confirm compatibility.
How does the UV stabilisation work?
The plastic material has been treated with additives that help to slow down the degradation process caused by exposure to ultraviolet (UV) radiation from sunlight, increasing the product's lifespan.
Does it come in different colours?
This specific model (ABC9TC) is the roughcast finish. Rytons offers other variants, such as a white version (ABC9WH).
Troubleshooting
Cowl appears loose after installation.
Ensure appropriate fixings are used for the wall type and that they are securely tightened. Consider using additional fixings if necessary.
Excessive water ingress around the cowl.
Check that the cowl is sealed effectively against the wall. Ensure fixings are watertight and consider using a suitable sealant around the edges if persistent issues occur.
Reduced airflow is noticeable.
Inspect the cowl and the opening behind it for any blockages, such as leaves, debris, or animal nests. Clean thoroughly to restore free area.
Cowl shows signs of UV degradation (fading, brittleness).
While UV stabilised, extreme long-term exposure can eventually cause wear. Inspect periodically and replace if significant degradation compromises performance or appearance.
