Simpson Strong-Tie connectors make projects easier to build while making them stronger and safer. They are engineered and tested to perform and are manufactured to the highest quality standards. The embedded truss anchor series provides an engineered method to properly attach roof trusses to concrete and masonry walls. Simpson Strong-Tie provides two different moisture barrier plates between the concrete/masonry and truss. The TSS is a preassembled, companion product of the META embedded truss anchor, and the TBP8 seat plate also provides a moisture barrier installed prior to truss placement.
