Kastar Hand Tools, a brand of A'E Hand Tools, introduces their Magnetic Retractable Test Leads for testing electrical circuits. When users pull the leads out they will stay at the desired length, and afterwards can be rewound back into their protective case. Each lead consists of 18-gauge copper wire and has insulated alligator clips. New magnetic test leads are available in 3 x 10' (No. 1135) or 2 x 30' (No. 1138) options.
