This is an extension hook for the rear gate of a Unic loading vehicle. It's a latch. (Easy one-touch installation without tools.) It has a 2-stage adjustment, allowing you to change the angle. Easily adjustable with two bolts. This item, whether new or used, is rarely available. How about taking this opportunity? Item: (New) Made of steel (Chrome-plated) Set of 1 for left and right Reference Price: New Manufacturer's suggested retail price: 94,750 yen. Do you ever think, "I'm so close to being able to load a large vehicle like a Celsior or Fuga" with a 5m bed, etc.? Attach the extension hook and tilt the gate, and you can load it!! If you don't secure the gate and let it dangle, it's dangerous, and it can end up hitting the bumper when it bounces? This hook is recommended!! How about keeping it in your vehicle for emergencies? Easy to install without tools. Please ask any questions. Thank you.
