Masonry Connection Sleeve
Upgrade retrofit or new-build masonry to provide structural upgrade to masonry by combining cavity wall ties with bed joint reinforcement.
Thor Helical Masonry Connection Sleeves combine the structural performance of cavity wall ties and bed joint reinforcement to upgrade retrofit or new-build applications to provide structural upgrade to masonry. The system interlinks the cavity tie with helical reinforcement bars in the bed joint — creating a fully integrated masonry restraint system.
