A rope grab (open type) is a fall arrest or positioning device that can be manually attached or detached from a lifeline at any point, offering flexibility in safety systems. It’s commonly used in vertical lifeline systems for climbing or maintenance work.
A rope grab (closed type) is a fall arrest device that is permanently installed on a lifeline and moves with the user during vertical climbing but locks automatically during a fall. Unlike the open type, it cannot be removed or installed mid-line.
