3M Wire Connector - R/Y Spring Pkg/500

The Performance Plus connectors provide maximum protection and wider wire range. It incorporates a long flexible skirt with a rigid top, enabling the connector to conform in a box while protecting the connector and covering over strips. And it has a square wire spring that grips quickly, turns on fast and expands to accept a wide range of wire sizes - biting into conductors for a solid, secure connection. Because of their increased wire range, just three Performance Plus connectors handle the work of eight standard connectors.
