Key-Locking Mobile Radio Mounting Kit

The Motorola RLN4779A is a key-lock mounting kit designed to securely install compatible Motorola mobile two-way radios inside a vehicle. Its locking design helps prevent unauthorized removal of the radio from its mounting position.

This heavy-duty mounting solution is ideal for commercial fleets, public safety vehicles and other installations where radio security is a priority. Authorized personnel can unlock the mount when the radio needs to be removed for service, replacement or vehicle reassignment.

The RLN4779A provides a more secure alternative to a conventional non-locking trunnion bracket while keeping the radio accessible for normal operation.
