Anti-Static Wrist Strap Static electricity can be a real shock to a vehicle’s delicate electronic system. Simply by sliding across the upholstery and then touching an ECM circuit or terminal, a technician can cause sufficient damage, requiring replacement of the complete ECM. But wearing this one-size- fits-most, anti-static, wrist strap will virtually eliminate the possibility of this happening. The technician can work on electronic components without worrying about static damage. Includes a 6' coil cord with alligator clip and adjustable wrist strap. No. 7744 – Anti-static wrist strap. Wt., 4 oz.
