About this product

Galvanized Cable I-Beam Horizontal Lifeline System

Extremely lightweight and portable, these systems incorporate a modular, multi-base design that accommodates a wide range of steel and concrete beams. Spans can be up to 60 ft. (18.3 m) and with the optional bypass brackets, the system can be configured to run indefinitely for ultimate job site flexibility.

You can always depend on 3M's horizontal safety systems for mobility and fall protection when working at height. That’s why safety engineers and site directors choose DBI-SALA® horizontal lifelines. 3M offers the broadest selection, as well as significant advantages in safety and productivity. A horizontal lifeline may appear to be a basic line strung between two anchors, but it is not. It is critical to choose a system that has been precision-engineered and rigorously tested to meet regulations. These systems are used to protect workers operating in the horizontal plane who may not have continuous access to suitable anchorage points.
