The SPH is a heavy U-shaped strap designed as a stud-to-plate connection to resist roof uplift. This heavy U-shaped strap has a horizontal portion that bears against the wood wall top plates or sill plates and two vertical legs that are nailed to the edges of a wood stud. This tie is a cost-effective option when properly installed before the placement of the wall. SPH 3-9/16 in. x 8-3/4 in. ZMAX® Galvanized Heavy-Duty Stud Plate Tie (Pack of 3600).
