WSWH-HSR Strong-Wall® High-Strength Wood Shearwall Extension Kit

The WSWH-HSR high-strength wood shearwall extension kit is replacing the WSW extension kit. WSWH accessories are compatible only with WSWH panels; use WSW accessories with WSW panels.

The WSWH-HSR is designed to work with Strong-Wall® high-strength wood shearwall anchor bolts (WSWH-AB and WSWH-ABHS) for attaching high-strength wood shearwalls (WSWH) to concrete foundations. This high-strength rod kit allows for anchorage in tall stem wall applications where full embedment of a WSWH-AB into the footing is required. The head is stamped for identification with a No-Equal® symbol for identification, bolt length, bolt diameter and “HS” for high strength. The WSWH-HSR is not for use in place of WSWH-AB anchor bolts.
