Introducing the HDUE Holdown
The patent-pending HDUE is the next generation of holdown technology — engineered for residential and light-frame commercial construction. Building on the legacy of the HDU, the HDUE offers closely aligned dimensions with significantly enhanced performance and stiffness.
Why specify the HDUE?
- Full compliance: US code-listed with ICC evaluation for total peace of mind.
- Superior engineering: Features an extruded seat and overlapping back plate for maximum durability.
- Smarter load distribution: Innovative teardrop-shaped holes and heavy-duty washers transfer high loads more effectively.
- Efficiency in installation: Uses a combination of perpendicular and angled fasteners to achieve high capacities with fewer screws.
Available sizes and capacities
Rated for load capacities ranging from ~40kN to 100kN, the HDUE is available in three sizes:
- HDUE9
- HDUE13
- HDUE17
