Terminal Cup Washers

Terminal cup washers are formed like basic cup washers, but with a notch or cutout on the side. This notch is used to accommodate wires in electrical applications. These washers’ main purpose is to secure and retain wires and avoid slippage, to provide a safe and stable connection. Terminal cup washers are used primarily in terminal blocks, junction boxes and other electrical assemblies.
