Together, the HDUE holdown and SABR anchor bolt provide a stronger, faster way to secure shearwall end studs to concrete foundations.
The HDUE is a new generation of higher-performing holdowns that are an easy, one-to-one replacement for our previous model — the HDU. The code-listed, patent-pending HDUE is engineered to meet higher demand loads.
The code-listed SABR is a cast-in-place bolt that provides concrete anchorage for attaching the HDUE. The SABR anchor bolt replaces our SB and SSTB anchor bolts. SABR features a 6" threaded section that accommodates a variety of holdown seat heights, including all Simpson Strong-Tie holdowns, when installed on a 2x or 3x sill plate. And a one-piece, sweep design allows it to be placed close to the edge of the concrete while increasing strength.
