The WB2637 is a hypoallergenic ESD fabric wrist band set with a 6ft coil cord with 1 meg resistor. The soft, red woven fabric and 360°curved buckle of the wrist band allows the skin to breathe and makes it very comfortable to wear. The band uses hypoallergenic silver-plated nylon thread for conductivity and has a maximum resistance of 160 ohms. The standard band is standard with a 4mm snap. The coil cord's 2.5mm polyurethane coil insulation offers excellent coil memory and a swivel type banana jack increases coil life and prevents cord tangles.
