Leviton Telcom 4720-B Plug Lock 2-pole 3-wire

Product Description

The LEVITON TELCOM 4720-B is a plug lock device designed to secure electrical plugs in their receptacles and prevent accidental disconnection. It is a 2-pole, 3-wire configuration finished in an all-black housing. This type of plug lock is a hardware accessory used in commercial, industrial, and institutional settings where maintaining a secure electrical connection is critical.

Typical install scenarios include data centers, medical facilities, manufacturing floors, and anywhere that an accidental unplug could cause equipment damage, data loss, or a safety hazard. It is sold as a single unit per package.
