Multi-Contact MC4 Safety Locking Sleeve

Safety Locking Sleeve for MC4.

Use the MC4 Locking Sleeve when solar modules are equipped with Multi- Contact Type 4 clickable connectors. In order to comply with the 2008 National Electric code for accessible arrays, the plug connection must be secured with the UL approved, pluggable safety lock clip (PV-SSH4).

Once the clip PV-SSH4 is installed, the PV plug connection can only be unlocked using the PV-MS tool.
