Simpson Strong-Tie ACBH3X15.37-R1 Installation Overview

1. Use all specified fasteners; install horizontal screws first, then inclined screws.
2. Centerline notch at the top of the part can be used to help locate the connector on the wood member.
3. Do not overdrive SDCF screws during installation of fasteners. Predrilling lead holes for the SDCF screws is recommended if wood members tend to split or if driving the SDCF fasteners at the proper angle is difficult due to wood grain resistance.
4. Rout carried and/or carrying member according to application needs. The minimum recommended rout width and length is 1/16″ larger than the tabulated part dimensions.
5. A 1/8″ minimum to 1/4″ maximum gap is recommended between the carried and carrying members to prevent wood-wood binding during field assembly.
6. When attaching to the end grain of glulam members with multiple piece laminations across the width, refer to the manufacturer’s guidelines for more information.
