Wrist strap

Also known as a antistatic strap or antistatic wrist strap, a wrist strap is a strap that wraps around the users wrist like a bracelet and has a cord or other connection coming from that bracelet that attaches to the device being worked on, clips onto, and/or plugs into. The wrist strap keeps the user grounded, which helps prevent electrostatic damage to the device being worked on. Below are some examples of how a user would properly use an antistatic wrist strap.

• While working on a computer you could place your wrist in the strap and attach the other end (often using the alligator clip) to a metal portion of the computer case.
• While working with a electrostatic sensitive hardware you could place your wrist in the strap and plug the other end into an antistatic mat the device is laying on or into an antistatic workbench.
