Timloc LOC1204 Underfloor Vent Vertical Extension 150mm Box of 20

These 150mm Timloc Underfloor Vent Vertical Extensions are designed to work with the Telescopic Underfloor Ventilator to bridge gaps between its upper and lower sections and add two extra brick courses in height. They are intended for height differences over five bricks, allowing each ventilator section to extend over six to seven bricks and providing an additional 75mm in height. Constructed from robust, durable, and decay-resistant materials with a sleek black finish, they maintain unrestricted airflow through the main ventilator and do not require on-site modifications during installation. Lightweight and easy to handle, the extensions offer a practical solution for enhancing underfloor ventilation systems and ensuring continued performance over time. Each box contains 20 extensions, supporting efficient installation across multiple projects.
