## Questions & Answers

**Q: How do you release it so you can put on ball? It’s stuck in place abd can’t lift handle**
A: Squeeze the release trigger if that doesn’t work push down hard on the trailer tow listen for a click and then pull the trigger in before lifting the tow in one firm action

**Q: What are the dimensions and weight? Where is the integral lock Mp478b fitted?**
A: The internal width fits perfectly over a 50mm x 75mm box tubing I’ve used 3mm tube I’ve bolted through the 75mm depth of the box as for locking I see what looks like a key placement but haven’t figured that out but once hitched I can slide an 8 mm bolt behind the visual slide mechanism which prevents the release handle from sliding to the release position

Delivery was made to the wrong house. Delivery company said it was left in a "SHED" on my property. It was put in a small outside cupbaord on next door's property.. The item itself was great and works perfectly.
