What is IEC LOCK? 
Patented Secure Locking Mechanism 
IEC Lock® is a unique patented solution that securely locks into any standard C14 or C20 inlet. It prevents accidental power disconnection without requiring special inlets or modifications.

Protects Critical Equipment & Data
Designed for computers, servers, and sensitive electronic equipment, IEC Lock® helps safeguard valuable data and mission-critical systems by ensuring a continuous, reliable power connection.

Ideal for High-Vibration & Data Environments
Available in lockable Female C13, C15, and C19 connector versions, IEC Lock® is perfect for in-rack power within data centres and environments where vibration or movement could cause standard power cables to disconnect.
How it works
Pull back tab to insert 
Pull the tab back and then push the connector into any standard IEC inlet, release the tab and it is locked in position.
Automatic lock on release 
Once inserted, releasing the tab engages the internal latch, securing the connector firmly in place. Connector CANNOT be accidentally pulled or vibrated out of the inlet
Simple pull-back to disconnect 
To remove, pull the top tab back again to disengage the lock, then withdraw the connector.
