Hubbell HBL1224RKL 4-Way Locking Dimmer

The Hubbell HBL1224RKL is a 20 A, 4-way locking switch designed for 120/277 V AC lighting circuits. Its barrel-key lock prevents unauthorised operation, making it suitable for commercial corridors, stairwells and public areas where tamper resistance is required.

Verify circuit voltage

Confirm the branch circuit supplies 120 V or 277 V AC and that the box accepts back or side wiring with screw terminals. The switch accommodates 14 AWG to 10 AWG conductors and carries a 1 1/2 hp motor rating, so ensure the load does not exceed these limits.

Impact-resistant stainless steel body withstands

The stainless steel construction resists impact and corrosion during sustained daily operation. Locking barrel-key action maintains positive contact without loosening, and UL listing confirms compliance with applicable safety standards for continuous service.
