MSA Screw-Fixed D-Shaped Anchor Connector is a device fixed to structures, designed to bear the load of the entire fall protection system. Selection primarily depends on the application scenario. Careful consideration of the working environment is necessary, especially the structure at the connection point, such as I-beams, scaffolding, and concrete. The number of users should also be noted. 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 Screw-Fixed D-Shaped Anchor Connector is a permanently fixed anchor connector; it can be installed on the flange of I-beams; intended for horizontal installation positions.
