Simpson Strong-Tie Achieves UL-Listed Fire Protection Ratings on RTUD and ATUD Strong-Rod Components
Simpson Strong-Tie, the leader in engineered structural connectors and building solutions, announced today that the RTUD and ATUD take-up components of its high-performance Strong-Rod® anchor tiedown and uplift restraint systems are now UL listed as through-penetration firestop solutions when used in conjunction with Simpson Strong-Tie bearing plates.
Designed for securing mid-rise wood-framed buildings against forces caused by seismic and wind events, Strong-Rod systems include ratcheting take-up devices (RTUD) and expanding, screw-style take-up devices (ATUD) that work with the threaded rod assembly to compensate for wood shrinkage, providing a constant, continuous load path for maximum resilience to seismic and high-wind events.
