The patent pending HDUE holdown is designed to meet the increased design demands of today's residential wood structures, including three-story homes with more windows and limited shearwall space. Offering higher load capacities than previous models, the HDUE serves as an easy one-to-one replacement for our industry leading HDU. This holdown provides exceptional overturning resistance for shearwalls, braced wall panels and other lateral force-resisting applications in wood construction. The HDUE features a pre-deflected seat that reduces deflection under load, an overlapping back plate for increased strength and optimized screw patterns to prevent splitting. It's tested to ICC-ES AC155 standards. The higher-capacity models combine fasteners in both shear and tension while reducing the number of screws required. The HDUE installs with Strong-Drive® SDS heavy-duty connector screws, minimizing fastener slip and preserving the wood post's net section better than bolts.
