Simpson Strong Tie’s H1 Seismic/Hurricane anchors were designed to provide wind and seismic ties for trusses and rafters. The line may be used for general tie purposes, strong back attachments and as all-purpose ties where one member crosses another.

Following the H1 (shown, diagram) and the H2, the new H2A is an improved version with up to 575 pounds of uplift capacity – more than 200 pounds of additional uplift than the H2. It attaches to the stud, providing a continuous load path from the rafter/truss to the stud.

The nice thing about these structural products is that there’s minimal nailing into the top plates, which both eases installation while contributing to the uplift capacity.

Other anchors include the H10A attaches to double top plates and provides up to 1340 pounds of uplift capacity when attached to a Southern Pine truss. This is nearly as much uplift capacity as the H14, yet lower in cost and easier to install.
