Kitaco Ultra Robot Arm Lock HDR-10. This is a used item. I am selling it because I no longer use it. Regarding the sale: - Replaced with a new cover - Greased the moving parts - Simple cleaning Tip shaft section: 34mm Main square lock section: 28mm Total length: 2100mm Weight: 17kg Included items: Serial card 2 keys Instruction manual Thank you. There is some rust, but operation, unlocking, and locking are not a problem at all. With its reassuring thickness and length, how about using it as your main lock? Thank you.
