One size adjusts to any size wrist to provide reliable protection. The wrist strap features a band made of a silver plated, monofilament, continuous thread woven together with elastic nylon to maintain full conductivity, comfort and reliability, while providing rapid and continuous drain of static charge. Two-one megohm resistors are built into the ground cord. Adjustability also simplifies ordering procedures and inventory control by eliminating the need to order and stock several band sizes.
