Swing Away Tongue Trailer Lock

Swing Away Tongue Locks come in two diameter options:

  • 1/2″ diameter pin (DSWT12)
  • 5/8” diameter pin (DSWT58)


  • $0.00


Most boat owners prefer a lock in their swing tongue versus the pin that comes from the factory. Now that you can get DuraSafe’s Swing Tongue Lock keyed to our Receiver and Coupler Locks, convenience has never been easier. Using these three DuraSafe locks together keeps your trailer safe and secure.

The DuraSafe Swing Tongue Lock can also be used to prevent trailer theft. Remove the lock, swing the tongue open and reinstall the lock. This makes it impossible to straighten out the tongue and stops a would-be thief from hooking up your trailer and driving away.
