About this item
The ABUS 83/45-300 S2 is a rekeyable solid brass padlock rated at ABUS Security Level 8, fitted with a Schlage C keyway cylinder and a 1-inch shackle height. The shackle diameter is 5/16 inch and the shackle width is 1 inch, dimensions that fit standard hasps, chain links, and gate hardware sized for this range. The solid brass 1-7/8-inch body pairs a high-precision pin tumbler cylinder with a special alloy steel shackle carrying NANO PROTECT coating for extreme corrosion resistance. The cylinder is field-rekeyable and the shackle can be exchanged without tools. SKU: 83/45-300 S2.
ABUS 83/45 shackle diameter and dimensions for this configuration
The 83/45-300 S2 has a shackle diameter of 5/16 inch, a shackle height of 1 inch, and a shackle width of 1 inch. The padlock body width is 1-7/8 inches. These are the dimensions to confirm against the hasp staple opening, chain link inside diameter, and gate latch hardware before ordering.
The 1-inch shackle height is the standard configuration for the 83/45-300 S2. The 83/45 body also accepts replacement shackles in 2-inch, 3-inch, 4-inch, and 6-inch heights if the application requires additional clearance. Shackle changes are performed without tools. For replacement shackles and ABUS padlock accessories, the padlock parts and accessories catalog covers the available options.
How the Schlage C keyway configuration works for rekeying the 83/45-300 S2
The 300 designation in the model number refers to the Schlage C keyway. This is one of the most widely installed commercial key profiles in the United States, found across door hardware in offices, schools, healthcare facilities, government buildings, and commercial properties. A facility already operating on Schlage C cylinders across its door hardware can rekey this padlock cylinder to match the existing master key or grand master key system.
Rekeying is possible because the 83/45 S2 cylinder uses a patented pinning window that allows the cylinder to be removed from the padlock body, repinned to the target key cuts, and reinstalled. No padlock replacement is required. The cylinder, key system, and any keying arrangement stay in place when a shackle is changed. For Schlage C-compatible key blanks and cylinder cores, the cylinders, cores, and keys section covers the available options.
What the patented Z-Bar and NANO PROTECT shackle provide on this padlock
The Z-Bar is an ABUS-patented mechanism that converts the cylinder between key-retaining and non-key-retaining operation within seconds and without tools. In key-retaining mode, the key cannot be withdrawn from the cylinder while the shackle is open, preventing the key from being accidentally left in an unsecured lock. In non-key-retaining mode, the key can be removed at any point regardless of shackle position. The same padlock handles both operational requirements depending on the protocol at the installation site.
The special alloy steel shackle uses NANO PROTECT surface treatment, an ABUS corrosion barrier rated for outdoor, coastal, and high-humidity environments where standard shackle plating degrades over time. At Security Level 8, the 83/45-300 S2 is suited to securing high-value assets, grating enclosures, gates, storage units, tool containers, cellar windows, switchboard panels, and barrier hardware.
