Whether your need is for a system that installs to concrete column tops, clamps to an i-beam on a pipe-rack or is welded to a transmission substation, this system can be configured with different bases to provide your fall protection solution. You can always depend on our 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. We offer 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.
