About this item
The ABUS 83KNK/45 S2 is a rekeyable solid brass padlock body rated at ABUS Security Level 8, supplied without a cylinder. The KNK designation means this padlock ships as a body-only unit for buyers who are supplying their own cylinder to match an existing key system or who need to source a specific keyway not available in a pre-configured model. The 1-7/8-inch solid brass body includes the patented Z-Bar mechanism and the special alloy steel shackle with NANO PROTECT coating. No cylinder is included. SKU: 83KNK/45 S2.
What the KNK designation means and who this padlock is for
The ABUS 83KNK/45 S2 is the body-only version of the 83/45 S2 rekeyable padlock line. It ships with the Z-Bar mechanism, the NANO PROTECT shackle, and the S2 rekeyable chassis fully assembled, but without a cylinder installed. This configuration is the correct choice when the buyer already has a specific cylinder on hand, is sourcing a keyway ABUS doesn't pre-configure for the 83/45, or needs to install an interchangeable core for a facility-wide key system that operates on IC cores rather than standard pin tumbler cylinders.
Facilities running a building-wide master key or grand master key program often source padlock bodies separately so the keying authority remains with the facility locksmith or key control manager. Supplying an uncylindred body ensures the padlock can be keyed into the master key system at the time of installation rather than arriving with a factory random key cut. For compatible cylinders, cores, and key blanks across all major keyway profiles, the cylinders, cores, and keys section covers the available options.
How the patented Z-Bar and S2 rekeyable system work without a factory-installed cylinder
The Z-Bar is an ABUS-patented mechanism that converts the padlock between key-retaining and non-key-retaining operation within seconds. In key-retaining mode, the key cannot be withdrawn from the cylinder while the shackle is open. In non-key-retaining mode, the key can be removed at any point regardless of shackle position. The mode switch requires no tools and is reversible at any time. These functions operate through the Z-Bar mechanism itself and are fully functional once a compatible cylinder is installed.
The S2 designation confirms the padlock body is built to accept a removable cylinder through the patented pinning window design. Once the correct cylinder is fitted, it can be removed, rekeyed to a different key cut, and reinstalled without replacing the body, shackle, or Z-Bar mechanism. This is the same rekeyable architecture used across all 83/45 S2 models with factory-installed cylinders.
Shackle specifications and body dimensions for the 83KNK/45 S2
