The Manthorpe Eaves Closure Unit prevents the entry of birds and large insects into the building structure through the base of the roof verge. The GDV-REC Eaves Closure can be nailed into the barge board. The first Dry Verge Unit is then clipped securely 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, with the rebated unit allowing adequate clearance for any extended guttering.
