The Squids 3785 Split Ring Tool Attachment is designed to create a larger retrofit attachment point on tools with small captive holes for tethering tools up to 2 lbs, preventing dropped or falling objects from occurring on the job. Connection points for tool lanyards can be tricky to find, especially on smaller hand tools with small captive holes. While working at heights, it is important to tether tools as part of your overall fall protection plan, but the lack of these connection points can make that difficult.
