The Squids 3745 Tool Grip and Tether Attachment Point 2-pack installs onto screwdrivers and nut drivers to create a retrofit attachment point for tethering tools up to 1lb // 0.45kg, 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 like screwdrivers and nut drivers. 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.Designed in two pieces, this tool attachment features an end cap and a rubber sleeve. To install, slide a screwdriver or nut driver into the rubber sleeve and plug the end caps pegs into the reinforced holes of the rubber sleeve. The sleeve features a textured rubber and is ergonomically designed to cover the entire tool handle-providing greater comfort, torque and an enhanced grip.
