How to use: First, decide whether you want to attach the Beal Attract Tool to your harness shoulder strap or hang it from your waist belt. Then, place your tethered metal hand tool or small metal objects like screws and fasteners on the magnetic plate. When you need to use the tool, simply reach out and grab it. Note: Make sure the connections are secure before using the tool at height. Also, don't overload the magnetic plate with too many heavy objects. Maintenance: Regularly check the 4 connection holes and the 2 wire - gated clips for any signs of wear and tear. Wipe the magnetic plate clean to keep its magnetic strength.
