The IronRidge FF2-01-M1 FlashFoot2 eliminates the need for separate standoffs, flashings, and L-feet for attaching XR Rails to composition shingle roofs with an all-in-one design. This integrated design combines structural and waterproofing elements into a single unit. The entirely rebuilt system features a raised and encased water seal, providing redundant layers of protection against water entry. Furthermore, the twist-on cap protects the rail attachment and correctly lines it with the lag bolt, maximizing the mechanical strength of the connection.
