Timloc Horizontal Rear Extension Sleeve FOR 1201 Floor Vent Black 1206

The horizontal rear extension sleeve is designed for use with the 1201 floor vent and helps bridge wider cavity walls or thicker internal walls, up to a maximum of 200mm. This accessory fits into the lower rear opening of the main telescopic underfloor ventilator to extend its reach as needed without hindering airflow.

On site, this sleeve is commonly applied when building with cavity widths between 50–150mm or internal walls over 100mm thickness. Its lightweight design aids quick installation and handling, reducing the need for custom on-site adjustments. The material resists decay, making it suitable for ongoing use in various building environments.
