Review: Perfect security for your Hitch - The lock firstly comes in it's own bag making it easy to throw in a front locker during towing or storing in a garage out of season with no worries of rust or damage. Secondly the hitch lock feels quality with its lock and tow ball stopper also inspiring confidence when fitted. The added guarantee shows the companies belief in their product and it shows. This is also in that perfect value range making it affordable and secure. The bright orange colour makes it easily visible and a great deterant. These things aren't supposed to be light and yes it feels weighty but personally that was what I was after from this product
Review: Perfect fit for Al-Ko heads - I've bought this for my caravan, and it looks sturdy and easy to fit. Nice orange colour too with no plastic to fade in the sun. You can use it when stopping at service stations (but don't tow with it attached as that's dangerous). Fast delivery too, well packed.

## Questions & Answers

**Q: I have one but snapped key in lock. Anyone know where I can buy just the lock/barrel please**
A: Contact the manufacturer- you’ll get a new lock and key

**Q: Does it fit over the longer Alko 3004 hitch rear bolt ok?**
A: yes

**Q: Will this fit at 2017 Lunar Quasar 544?**
A: I assume so - it fits any 'normal' AL-KO hitches.  The photos on the listing are pretty clear.

**Q: Can it be fitted when caravan is attached to towing vehicle to prevent theft whilst hitched to car?**
A: Yes while parked up but it is recommended by the emergency services not to leave it on when driving. It's just in case they have to separate the caravan from the car quickly in an emergency.
