Manthorpe Refurbishment Slate Vent 600mm x 300mm (10000mm2) - Black

This Refurbishment Slate Vent by Manthorpe is the perfect solution for retrofitting without cutting slate battens. It is manufactured as standard for 600 x 300 slates but can be trimmed easily to fit 500 x 250 slates using the pre-marked cut lines.

Also seen as the alpha slate vent, it's usable for high and low-level roof ventilation requirements. The hood features a 4mm fly screen to prevent blockage from falling debris and prevent large insects from entering the roof space. Manufactured from UV-stabilised polypropylene, this contributes to its long lifespan, plus allows 10,000mm² airflow per vent for reliable roof ventilation.
