The FRFP is designed to connect the mudsill to the foundation and provide lateral load resistance. This flat retrofit foundation plate features a design that allows the designer to maintain prescriptive requirements. The FRFP can be used by filling the three round holes, or as an alternative, filling two optional triangle holes to allow designers increased loads and greater spacing. FRFP 7 in. x 9 in. Retrofit Foundation Plate (Pack of 5).
