Telescopic Underfloor Vertical Vent Extension Piece

Telescopic Underfloor Vertical Vent Extension Piece designed to extend the vertical reach of a primary telescopic underfloor ventilator system. This modular component connects directly to the main vent body, increasing the effective depth between the external air brick and the sub-floor void. Manufactured from UV-stabilised, weather-resistant polypropylene, it delivers long-term durability in damp or below-ground conditions. By maintaining a continuous and unobstructed air pathway, it ensures that fresh air is drawn in and moisture-laden air is expelled efficiently, even where deeper foundations or irregular ground levels exist.
