Apply starting piece and slide the Dry Verge Unit (pointing to towards the apex) until the Verge unit butts up against the end of the first tile. Screw the Verge Unit through the top and bottom holes, so that the screw penetrates the barge board or brick and firmly holds the Dry Verge in place.
Clip together a second Dry Verge Unit and push it onto the tail of the first, until both slides of the clip engage with the tail fins of the first. Once again ensure the Verge unit butts against the end of the tile. Then screw the tail end of the Verge Unit through the rear hole so it attaches to the barge board.
Repeat instruction 2 until all tiles have been covered. Once the left hand verge is completed, repeat on the opposite verge using the right hand verge units. The ridge cap is then securely screwed into the dry verge.
