The Kingwin ATS-W24 Anti-Static Wrist Strap is a high performance band with a built-in grounding wire that protects your PC or other electronics device from static electricity build-up. This wrist strap helps you by creating a "path to ground" that will dissipate any static charge you would otherwise send through the hardware you're working on. That means your sensitive hardware is protected from static shock. It also features an extra-long coil cord for wide range of movement for your convenience. This antistatic band is highly adjustable and will fit almost any wrist comfortably.
