Description
The Manthorpe Extension Sleeve is an essential accessory for enhancing the functionality of Manthorpe’s range of telescopic underfloor void ventilators. Each sleeve provides an additional 150mm of extension, equivalent to two extra courses when used vertically, making it ideal for deeper underfloor voids. For horizontal applications, the sleeve can be seamlessly attached to the base of the G960 or G965 telescopic ventilators, allowing for effective extension through larger cavities or wider internal blockwork.
Packaged in a convenient pack of 20, these extension sleeves offer a flexible solution to meet various building requirements. Easy to install and compatible with the entire Manthorpe telescopic ventilator range, the G961 Extension Sleeve ensures optimal ventilation performance and adaptability for diverse construction scenarios.
