Description
The 115mm Timloc Underfloor Vent Horizontal Front Extension (LOC1203) is a practical solution for extending telescopic underfloor ventilators through thicker walls. Fitting neatly between the air brick and the upper front opening of the vent, it accommodates external walls exceeding 102.5mm in thickness, up to a maximum of 215mm. This extension ensures consistent underfloor ventilation, helping to prevent dampness and maintain airflow in suspended flooring systems. Made from durable, weather-resistant plastic, it’s ideal for builders, contractors, and property maintenance professionals working on both new constructions and refurbishment projects.
