These copper butt splice connectors are used for joining cables of medium to low voltage, e.g. battery and primary / common power feeds. 

A bell mouth (flared/chamfered) entry ensures a smooth entry and transition between connector and cable. This avoids problems of chafing and pull-out, particularly where the connection is at risk of vibration.

Suitable for crimping only, please do not solder. 

The addition of an inspection hole means you can check the conductors are fully inserted into the terminal before you crimp.
