The disc lock is a special form of padlock with some distinct advantages. The disc shape effectively combats the most common ways of forcing it open. The design with only a small opening in the shackle makes it very difficult to tamper with. As the ABUS Diskusis made mainly of stainless steel, it is used especially where security and protection against corrosion are required. 360-degree all-round protection. The Diskusfamily is available in models with diameters between 50 and 80 mm. The original Diskusis only available from ABUS. As a special model, the locks can be retrofitted with a disc cylinder (ABUS-Plus locking system) or cylinder pulling protection.
