TRELOCK U-lock "U4"

U-locks U4Thanks to its bar made of special Tredur steel, the "U4" U-locks from TRELOCK offer comprehensive theft protection. The steel is specially hardened and therefore saw-proof, resistant to cold spray and extremely impact-, cut- and bend-resistant. The Lock therefore achieves security level 4 on TRELOCK's own scale of 1 to 6. The "soft" surface of the bar is also particularly gentle on bicycle frames. The lock cylinder is manufactured in such a way that the keys cannot fall out of the lock and can be inserted from both sides. It also has a dust cap for its own protection. Available in widths of 83 mm, 102 mm and 108 mm and shackle lengths of 230 mm and 152 mm (U4 Mini) as well as with Bracket.
