This is KITACO's strongest lock. It uses a key made by ABLOY, which is said to be used in the Louvre Museum and other places. ⚠️Only one key is included⚠️ For those who absolutely do not want their belongings stolen, or for high-end vehicles. We recommend locking the vehicle to the ground. I purchased it online, but I don't have a purchase history, so the model number is unknown. The approximate purchase date was around 2013, and the total length is about 185cm, according to my amateur measurement. It was stored outdoors, so it has some dirt, but I cleaned it as much as possible with OxiClean. The dirt is not completely removed. The key works without any problems, and the performance has not changed at all, so thank you. 【Note】Photos 4-6 are the latest version of the arm lock from the official page, so the actual product is a different version. The Ultra Robot Arm Lock TDZ series is a further improvement on the conventional robot arm lock, which is known for its ease of use due to its multi-joint design, making it even more user-friendly and robust. The extension of the tip shaft and the installation of a protective sponge cover make it less likely to scratch, and it is also easier to use with spoked wheel vehicles. Furthermore, the strength has been improved by changing the arm material. In addition, special rivets are used for the joints, making it very easy to attach and detach with very smooth movement. #KITACO #Motorcycle #Lock #TheftPrevention #Strongest
