New, Unused Retail Price: ¥3850 【High-Quality Key Cylinder Padlock】 The pure copper cylinder is precisely manufactured and highly durable. Bike locks used outdoors sometimes encounter problems where they cannot be unlocked. By using a high-quality cylinder, these issues are prevented. Please use key-specific lubricant regularly. 【Features of the U-Lock】 The U-lock is constructed from a single piece of steel, with no joints, making it lightweight and durable. While it offers less freedom compared to chain locks, its structure is highly resistant to destruction. 【Special Hardened Steel】 Using a special steel alloy and undergoing special hardening treatment, the U-lock has a high hardness that can withstand 15 tons of hydraulic shear. It employs 13mm thick steel, capable of resisting attacks from silent hydraulic cutters. The surface hardness from the hardening treatment further enhances shear resistance. Additionally, it is equipped with an anti-drill plate to improve security performance, providing resistance to drill attacks. It also features a square lock pin boasting a tensile strength of 4 tons, demonstrating excellent resistance against attacks such as U-lock extraction. 【Also as a Disc Brake Lock】 The U-lock with an inner diameter of 57mm can also be used as a disc brake lock. Rubber coating prevents scratches on wheels and brakes. ■ Anti-Drill Plate: Prevents key cylinder destruction by drills, etc. ■ Dust-Proof Shutter: The dust-proof shutter prevents the key cylinder from becoming unopenable due to foreign objects getting stuck, even in unpaved parking lots. 【Product Details】 ■ Padlock: Length 119.2mm, Width 107mm, Diameter 13mm, Inner Diameter 57mm ■ Materials: [U-lock] Special hardened steel, [Key Cylinder] Copper, [Case] Polycarbonate, [Sleeve] Rubber ■ Strength: Shear strength 15T, Tensile strength 4T ■ Set Contents: Padlock, 2 Padlock Keys ■ Weight: 552g ■ Instruction Manual (Online Only): As part of our decarbonization efforts aimed at reducing environmental impact, we have refrained from including a paper manual.
