Recommended Swing Away Tongue with Disc Brake Actuator and Reverse Lockout


I am looking at 4839100 coupler and the 4839120 coupler. Does the 4839100 come with electric lockout for backing trailer up. If not does 4839120 come with manual lock out. I need a way to manually disconnect electric trailer backup brakes Incase something happens so I can still back trailer up. I am wanting coupler for disc brakes that has both. I am trying to find a 2007 Ranger swing tounge replacement thanks.

The Swing-Away Actuator w/ Manual Lockout - Bolt On - Disc - 2" Ball - 7,500 lbs # T4839100 and the Swing-Away Actuator w/ Electric Lockout - Bolt On - Disc - 2" Ball - 7,500 lbs # T4839120 are similar just with the one having the manual option in addition. Because you are looking for both a manual and electric lockout option, I recommend getting the manual lockout # T4839100 which in the attached video shows an electric lockout as well. I went into the warehouse to confirm it does have both lockout options, so will be ideal for your application.

These actuators are made for 3 inch by 5 inch wide channel tongue, so for a 3 inch by 3 inch channel tongue you will need two spacers or for a 3 inch by 4 inch a single spacer will be needed. That spacer in either case is # T4842100.
