The top model U6 L from Trelock is identical in construction to the winner of the Stiftung Warentest test (8/2017, identical in construction) and is therefore one of the most secure locks in the Trelock range. A dust cap protects the IN-X inner track cylinder.With a shackle length of 23 and 30 cm, the U6 L is particularly suitable for connecting to fixed objects. The secure hardened steel shackle and the wide range of mounting options on the bicycle frame with the ZB 401 holder make the U6 L a valuable companion when it comes to theft protection. The U6 L can also convince visually, because it appears, like all product innovations from Trelock, in the new and noble product design. - Type: U-lock - Security level: 6 - Key: inner track milling on two sides, reversible key - Mounting: Flexible to mount on the frame - Locking cylinder: Cylinder lock, In-X - Theft protection: highest security - Details: - Dust cap - Sold Secure Gold, SBSC, FG - Closure type: Key lock Dimensions U-lock - U-lock diameter: 16 mm.
