35 (800) 521-9790 alpineitw.com General Notes: 1. Allowable load capacities based on species and load duration factor as permitted by applicable building code. 2. Minimum Southern Pine referenced compression design value for compression perpendicular to grain is 565 psi. 3. For face mount installation, when more holes in header flanges are available than required fasteners,fasteners must be evenly divided between header flanges and placed in the lowermost 4 holes in each header flange and the uppermost available 2 holes of each header flange, with remaining fasteners evenly distributed throughout remaining header flange holes. 4. For top mount installations, fasteners in top of header must be evenly divided between header flanges. The furthest fastener in each top flange from the hanger face of the header must be at least 2" for the STH218-2, STH418, STH222-2 , STH422 and STH426, and 2.25" for the STH29, STH29-2, STH422-2, STH426-2, STH422-2R and STH426-2R. 5. All fasteners must be placed a minimum of 1 ⁄4" from any edge of members. Fasteners in face of header must be evenly divided between header flanges and applied in the lowermost holes of each header flange. 6. STH hangers may be installed with one strap top mounted and one strap face mounted over header, use lowest of the top and face allowable load for connection.
