The ABUS Plus 88/50 is a rotating disc-detainer padlock made by ABUS. The inner cylinder uses seven code discs and two “butterfly” discs (or a butterfly and a zero disc) that interact with a sidebar. There are thin “spacer” washers in between each disc.
The 88/50 uses a dual ball-bearing locking mechanism.
Principles of operation
The ABUS Plus works by using angled bitting cuts on the key to rotate discs. The key is inserted and rotated 90°; the angled cuts on the key in rotate the discs in the lock. When all the discs are rotated to the correct position, the sidebar falls into the true gates and the plug can be rotated. Washers are placed between discs to ensure that the key rotates each disc individually. There are six positions available for discs, at 18° increments between 0° and 90°. The discs are numbered 1 – 6, with corresponding cuts on the key. The 1-cut is the deepest cut and does not rotate the disc. The 6-cut leaves the key uncut, and the #6 disc rotates the plug once the sidebar retracts. False gates are included on the discs with the intention of increasing the difficulty of lockpicking and decoding.
Disassembly instructions
In order to disassemble this padlock, begin by unlocking cylinder and lifting the shackle, and removing the screw beneath it. Carefully remove the small steel balls under the screw. Then the collar in front of the lock cylinder can be unscrewed and the cylinder removed. The actuator behind the cylinder and the ball bearings can be removed, as well.
