Square-body padlock for outdoor security

The Abus 83/55 RK KD-300 is a square-body padlock built for gates, sheds and storage units that need a hardened-steel shackle and a pick-resistant cylinder. Its weather-resistant finish and Schlage C keyway suit commercial and residential users who want a single lock that can be rekeyed later.

Hardened steel resists cutting and corrosion

A 7/16 in diameter hardened-steel shackle and a matching hardened-steel body withstand bolt-cutter attacks and prolonged exposure to rain. The 5-pin or 6-pin cylinder is keyed different from the factory, and the non-removable key prevents accidental key loss while the lock is open.

Replaces basic laminated or brass padlocks

Builders upgrading from standard laminated steel or brass models gain a square body that resists prying and an interchangeable core that allows rekeying without buying new hardware. The jump is worth it when the asset value justifies a high-security rating and a lock that can be master-keyed into an existing Schlage system.

Questions about this item

How do I install the Abus 83/55 RK KD-300 padlock and what step is commonly missed?

Slide the hardened steel shackle through the hasp or chain, push the body down until the shackle clicks into the locking notches, then remove the key; the step often missed is verifying the shackle is fully seated in both notches before turning the key.

What maintenance or replacement will the Abus 83/55 RK KD-300 need over time?

Periodically lubricate the 5-pin or 6-pin cylinder and shackle mechanism with a dry PTFE spray; because the core is interchangeable, a locksmith can rekey or swap the core instead of replacing the entire padlock.

What limit appears first on the Abus 83/55 RK KD-300 under sustained outdoor use?

The weather-resistant coating on the hardened steel body and shackle resists corrosion initially, but prolonged exposure to salt or industrial atmospheres will eventually degrade the finish and require more frequent lubrication.
