Abus 55/50 C KD Solid Brass Padlock,

The ABUS 55/50 C KD is a solid brass padlock rated at ABUS Security Level 5, supplied keyed different so each lock in a group operates on its own unique key. The 1-57/64-inch brass body pairs a precision pin tumbler cylinder with a 9/32-inch hardened steel shackle and non-corrosive internal components throughout. It self-locks when the shackle is pushed down without a key, weighs 0.48 lbs, and stands 2-43/64 inches in overall height. No hasp or cable is included.

How the ABUS 55/50 C KD fits the Security Level 5 range

ABUS Security Level 5 places the 55/50 C KD above the mid-range of the brass padlock line, suited to applications where the risk level calls for more than basic deterrence without requiring a high-security rated body. The solid brass construction resists corrosion in outdoor, coastal, and high-humidity environments, and the hardened steel shackle adds resistance to cutting attacks beyond what a standard shackle delivers. It's a practical fit for gates, storage units, equipment enclosures, lockers, toolboxes, cellar windows, sheds, switchgear panels, and cobra loop cable installations.

For applications where the threat profile requires Level 6 or above, ABUS offers padlocks with reinforced shackle locking points, hardened alloy bodies, and additional attack resistance. The 55/50 C KD's Level 5 rating positions it correctly for commercial and light industrial use where durability and reliable daily operation are the primary requirements.

What keyed different means on this padlock

The KD designation means each padlock in a purchase ships with its own unique key cut. No two locks in a keyed different order open with the same key, which makes the 55/50 C KD the correct choice for facilities where access separation is required. A storage unit complex, locker bank, or equipment yard where each secured point needs an independent key operates correctly on keyed different hardware. Each padlock includes two keys at time of purchase.

Shackle dimensions, body size, and installation compatibility

The shackle diameter is 9/32 inch and the shackle height is 15/16 inch, which fits standard hasps, cobra loop cables, and chain links without requiring an oversized staple opening. The body width is 1-57/64 inches and depth is 35/64 inch. Confirm the hasp staple opening accepts a 9/32-inch shackle diameter before ordering. The self-locking mechanism closes the shackle without a key, preventing the lock from being left open accidentally.
