An independent engineering corporation tested the performance of the Ventco Ridge Cap
Anchor Clip under high wind loading. During testing, a roof/ridge vent/cap system was
subjected to wind speeds that follow the Dade County Test protocol.
The following observations were made concerning the performance and structural
integrity of the clip and ridge cap:
No lifting of the ridge cap up to 115 mph
No fastener pull out or loosening
The ridge cap remained in contact with ventilation system
No difference in performance when the cap is secured to the clip with screws or blind rivets
1. Install your metal roofing panel according to manufacturer’s instructions. Apply mastic above and below pre-drilled holes in the clip. Before installing ProfileVent, insert #14A screw through the large down-slope access hole in top of the Ridge Cap Anchor Clip.
2. Lift the back end of clip. Slip ProfileVent under the clip. Push clip back down and insert another #14A screw in the up-slope hole.
3. Screw through ridge cap and top of each anchor clip. Rivets can be used to anchor the ridge cap when using architectural or standing seam panels.
