ULTIMATE 420 combines many advantages of its older siblings. Similarly to the Super Ultimate 430 model, the shackle runs along the entire body and is locked on both sides with the use of steel bolts for increased protection against twisting and bending. For better protection against cutting, crushing and bending, the shackle, that is a bit narrower than in the SUPER ULTIMATE 430 model, as long as the body and other important metal elements are made of hardened steel. The ULTIMATE 420 model features a soft plastic casing to protect the paint from scratches. Just like all ABUS locks, it offers a high resistance to rust.
