TITALIUM™ 90RK Series – Lightweight Closed Shackle Padlock

TITALIUM™ 90RK Series

ABUS TITALIUM™ 90RK Series – Lightweight Closed Shackle Padlock with Interchangeable Cylinder (All Variants)

The ABUS TITALIUM™ 90RK Series Padlock delivers an outstanding combination of high-security closed shackle protection, lightweight TITALIUM™ construction, and exceptional corrosion resistance, making it an excellent choice for demanding indoor, outdoor, and marine applications where maximum attack resistance and minimal weight are both essential. Built from TITALIUM™ special aluminium alloy — a proprietary high-strength, low-weight alloy — and fitted with a high quality stainless steel closed shackle, the 90RK Series provides serious protection against the full range of physical attack methods while remaining remarkably light in use.

Designed with a double bolted locking mechanism for high resistance against pulling and torsion, an integrated shackle guard to protect against bolt cutter attacks, and a precision pin cylinder that is fully interchangeable for re-keying to match existing locks, the 90RK Series provides dependable high-security protection with outstanding installation flexibility. Key retaining functionality is standard, ensuring the lock can only be secured with the key present and retaining it until locked — preventing accidental lock-outs and improving security discipline. Integration into master key systems is supported, and the stainless steel shackle provides superior resistance to corrosion in marine and coastal environments.
