The HG-BT-504 from Ground Zero is ideal for boots and cross-training athletic shoes. Constructed from durable materials and featuring a comfortable and secure D-ring closure, the HG-BT-504 provides protection for staff on the move. These heel grounders connect the person wearing them to ground via a proper floor mat or flooring material. Wearing the conductive ribbon inside the shoe or sock assures proper electrical contact with the user. The ribbon connects to the conductive rubber to complete the circuit between the operator and the static controlled floor or mat. A rugged 1 megohm resistor is standard and visible. Heel grounders are worn on both feet to provide consistent grounding while in motion.
