Designed for hobbyists and professionals, the blue Anti-Static Wrist Strap from Pearstone helps protect against static electricity that can damage a computer or other electric components that you may be working on. This strap features an adjustable semiconductive elastic band that helps to ensure a proper fit so that the conductive metal plate is always in contact with your skin, assuring a proper ground. Additionally, the coiled cable can expand in length up to six feet, helping to make sure that your mobility isn't restricted while working, and the durable crocodile clip securely attaches to the frame of your PC or other metal surface.
