Manthorpe's Eaves Closure Units are the starter unit for the SmartVerge systems and are also designed to prevent the entry of birds and large insects into the base of the first verge unit. The GDV-EC Eaves Closure should be affixed securely onto the structure of the building at the eaves, the first Dry Verge Unit is then clipped over the Eaves Closure providing a strong foundation for the remainder of the system. The design is ambidextrous in nature and can be used on both verges of the roof.
