Electric Coupling 3500kg Rated with 1/2 inch BSW ball adjusting nut.
The adjustment nut on the head of the coupling is a 1/2″ BSW thread.
This nut prevents the Electric Coupling from jumping on the tow-ball and creates and tight fit by removing slop that can occur through wear.
Electric Caravan Coupling Adjustment
To properly adjust this nut;
- Put pressure on the Electric Coupling, so it is firmly on the tow ball.
- Loosen the nut.
- The thread so you can feel it touch the top of the tow ball.
- Now tighten the locking nut being careful not to unscrew the threaded screw.
Finally, you have a cable adjustment to check.
The cable running down to each handbrake lever should be tight but not overly tight. Adjust the cable brake adjuster just behind your handbrake until this cable is taut.
One final thing, your coupling weight, when attached, should be around 8% of your total load. Your coupling should now be tight and ready to tow.
Sure, there are cheaper couplings on the market. We buy and recommend only the best products for your investment dollar.
