Two-by-six minimum wood framing is secured with ten-penny nails at six inches on center staggered. The design incorporates cant strips beyond the drain bodies and maintains a minimum five-inch clearance to surrounding deck elements. The top of the shield extends a minimum of two inches above the roof deck.
