How it connects
The projecting tongue engages the adjacent device’s matching groove to align the mounting straps during multi-gang installation. This is mechanical registration; it provides no electrical contact or fluid seal.
Male and female halves
Male denotes the projecting tongue; female denotes the receiving groove. The named interface is the tongue, rather than the complete electrical receptacle.
Usually connects to
- Matching groove on an adjacent compatible Leviton Lever Edge device mounting strap
Common sizes
- No dimensional interface specification is established for the Lever Edge alignment tongue.
Where it is used
Multi-gang electrical switch and receptacle installation
Variations
- Complementary female alignment groove
How to recognise it
Check the lateral edges of the broad mounting-strap areas above and below the device face for complementary projections and recesses. Confirm the product documentation identifies tongue-and-groove multi-gang alignment; the colored wire levers are separate features.

|---|---|
| NEMA 5-15R receptacle interface | NEMA 5-15R describes the electrical plug-receiving face. This tongue is a separate mechanical feature on the mounting strap. |
| Lever-operated wire terminal | The colored levers secure electrical wires at the rear; the tongue-and-groove features align adjacent mounting straps. |
