Each year, countless numbers of workers lose footing while carrying tools and materials up ladders due to the presence of grease, mud, snow, ice and water. Sadly, many of these ladder related accidents are preventable with the use of a vertical lifeline and a rope grab system. A vertical lifeline allows movement up and down the entire height of the line, eliminating the need to disconnect and find a new tie-off points while ascending or descending from a tower or ladder. By connecting to the vertical lifeline using a “rope grab” deceleration device, users may move as long as tension is slack on the lifeline. In the event of a fall, the rope grab automatically engages the vertical lifeline and locks, arresting the fall and potentially saving a life.
