Leviton Telcom 26W49 Locking Plug Lock L7-20

Product Description

The LEVITON TELCOM 26W49 is a yellow plug lock designed for use with 2-pole, 3-wire L7-20 locking connectors. Plug locks physically secure a mating plug to its receptacle, preventing accidental disconnection under vibration, load cycling, or high-traffic service conditions. The yellow color provides quick visual identification on crowded electrical panels or distribution equipment. This hardware accessory is typically installed by licensed electricians or qualified maintenance technicians working on locking-style branch circuit connections.

The 26W49 is suited for industrial, commercial, and heavy-duty residential applications where NEMA L7-20 locking plugs are in use. It is particularly useful in environments where cord pull-out or vibration-induced disconnection poses a safety or equipment risk, such as mechanical rooms, data centers, manufacturing floors, and temporary power distribution setups. Installation requires no special tools and takes only seconds per connection point.

Key Features

• Designed for NEMA L7-20 locking plug configurations (2-pole, 3-wire)
• Yellow color coding for fast visual identification in multi-circuit installations
• Prevents accidental plug disconnection under vibration or cord tension
• Sold as a single unit (each) for flexible quantity ordering
• Hardware accessory category — no wiring required for installation

Compatibility

Designed for use with 2-pole, 3-wire NEMA L7-20 locking plugs and compatible locking receptacle assemblies. Verify plug body profile before ordering, as locking plug lock fitment is configuration-specific.

Installation Notes

Installation should be performed by a licensed electrician or qualified technician in accordance with NEC requirements for the circuit type. Always de-energize the circuit and confirm the absence of voltage before handling plug and receptacle assemblies. The plug lock slides over or clips onto the mating plug-receptacle interface — no tools or fasteners are typically required. Inspect the lock for secure seating after installation to confirm it is fully engaged.
