MSA Welder's Special Anchor Strap, a device fixed to structures, bears the force of the entire fall protection system. Selection primarily depends on the application. The work environment must be carefully considered, especially the structure at the connection point, such as I-beams, scaffolding, and concrete. The number of users also requires attention. Most anchor connectors are designed for single-person use, with a minimum breaking strength of 22 kN (approximately equivalent to the force generated by a 2,200 kg weight). In some cases, when users need to move horizontally across a large area, such as an entire roof, a lifeline system should be considered; MSA will design engineered system solutions for you. The MSA Welder's Special Anchor Strap is made of Kevlar material and sewing thread, effectively preventing welding sparks. When paired with the Thermatek series products, it provides a complete solution for welders' working environments. Replaceable strap wear protection pads (accessories) are available.
