Abus 83S-IC/45 LFIC SCHLG Padlock

The ABUS 83S-IC/45 LFIC SCHLG is a Security Level 8 hardened steel padlock from the ABUS 83 Series, built to accept Schlage Large Format Interchangeable Core (LFIC) cylinders. The body and shackle are chrome-plated hardened steel with NANO PROTECT coating, the locking mechanism uses a double stainless steel ball deadlock, and the patented Z-Bar provides two locking modes in a single unit. The padlock ships less core. The Schlage LFIC core is not included and must be ordered separately. SKU: 83S-IC/45 LFIC SCHLG.

What the SCHLG and LFIC designations mean on this ABUS 83 Series padlock

LFIC stands for Large Format Interchangeable Core, the IC standard used by Schlage and a number of other major hardware manufacturers. The SCHLG designation confirms this padlock body is bored and configured specifically for Schlage LFIC cores, meaning the bore geometry, retainer slot, and core engagement format match the Schlage LFIC specification. This is not interchangeable with SFIC (Small Format Interchangeable Core) padlocks, which use a different core geometry and are used with a different set of brands.

Facilities that run Schlage LFIC cylinders throughout their building in cylindrical locks, mortise locks, and exit devices can extend the same cores directly into padlock applications using the 83S-IC/45 LFIC SCHLG, maintaining one unified key control system without a separate padlock keying arrangement. The core is not included with this padlock. For Schlage IC cores compatible with this padlock, the Schlage IC cores section covers the available options.

What the S body designation means: hardened steel versus brass in the ABUS 83 Series

The S in 83S identifies the body material as hardened steel. The standard ABUS 83 Series uses a solid brass body. The 83S uses a chrome-plated hardened steel body that provides meaningfully higher resistance to drilling, sawing, and cutting attacks compared to brass at the same body size. Both the body and the shackle on the 83S-IC/45 carry chrome plating plus NANO PROTECT surface treatment, ABUS's corrosion barrier rated for outdoor and high-humidity environments where bare steel or standard chrome alone would degrade over time.

The hardened steel body is the correct specification for high-risk or outdoor applications where physical attack resistance needs to match a Security Level 8 rating through the body as well as the shackle. The double stainless steel ball deadlock engages both sides of the shackle heel simultaneously, preventing lateral movement that a single-ball mechanism would allow under torsion or pry attack.

How the ABUS Z-Bar provides two locking modes in one padlock

The patented Z-Bar is an ABUS mechanism that converts the padlock between automatic locking and key-retaining mode within seconds. In automatic mode, pushing the shackle down locks the padlock without a key. The IC core is only required to open it. In key-retaining mode, the shackle locks only when the IC core is used to lock it, and the core cannot be removed from the padlock until the shackle is fully closed. This prevents the padlock from being left open by an operator who walks away before completing the lockout. Switching between modes requires no tools.

Shackle dimensions and easy shackle change compatibility

The shackle diameter is 5/16 inch and the vertical clearance is 63/64 inch on the standard configuration. The 83S-IC/45 is compatible with ABUS Easy Shackle Change, allowing the shackle to be swapped for a different height without replacing the padlock body or the IC core. Available shackle heights include 1-3/16 inch, 2-1/2 inch, 3 inch, and 4 inch. Confirm the hasp staple opening accepts a 5/16-inch shackle diameter before ordering. For replacement shackles and accessories, the cylinders, cores, and keys section and the broader ABUS catalog are available for reference.

Where the 83S-IC/45 LFIC SCHLG sits in the ABUS 83 Series IC padlock range

The ABUS 83 Series IC line covers both LFIC and weather-protected IC configurations. For a weather-protected version of the 83 Series padlock prepped for Schlage LFIC, the ABUS 83WP-IC/53 weather-protected LFIC SCHLG padlock is also stocked.
