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 predeflected 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. Available in multiple sizes, the HDUE accommodates a wide range of load requirements.

  • Predeflected seat reduces deflection under load
  • Angled fastening in the four larger sizes engages the screws in tension for higher load capacity, reducing the number of screws required
  • Angled fastening tabs in the four larger sizes help drive the fastener at a 45 deg angle and offset holes on the second back plate block the fastener from being driven straight
  • Overlapping back plate increases fastener strength and shear values, helping prevent post splitting
  • Optimized screw patterns reduce splitting at the end of the post and maximize individual fastener capacity
  • Installs with strong-drive SDS heavy-duty connector screws
  • Extruded seat adds a greater cross-sectional steel section for added strength
  • Teardrop holes allow higher and more even distribution of load
