Square hardened padlock for keyed-alike access

The Abus 83/55 RK KA-100 is a square-bodied padlock built from hardened steel with a hardened steel shackle. It uses a 5 pin or 6 pin cylinder operated by a Yale No. 8 keyway and is supplied keyed alike so multiple locks share one key. The lock body measures 2 11/64 in wide and 63/64 in thick, while the shackle clearance is 1 7/16 in high by 15/16 in wide. Weather resistance and a non-removable key add security for outdoor or indoor use.

Replaces individual keyed locks when managing

This padlock replaces sets of differently keyed padlocks where a single key simplifies daily access for maintenance staff, facility managers or property owners. The jump is worth it when you need interchangeable core flexibility and rekeyable cylinders without registering a control key. High security rating and hardened components resist physical attack better than standard laminated or brass-body alternatives.

Suits users who need one key for several identical

It suits buyers who want a weather-resistant, high-security padlock with a square hardened body and keyed-alike convenience. Builders who need a second card or buyers who want more storage should look elsewhere, as this is a single mechanical lock without electronic access, combination dials or smart connectivity. Anyone requiring a different keyway, removable core or longer shackle dimensions will need another model.

Questions about this item

What shackle diameter and clearance does the 83/55 RK KA-100 need to fit a hasp or chain link?

The hardened steel shackle is 7/16 in thick with a 1 7/16 in internal height and 15/16 in internal width, so the mounting hole or link must accept those dimensions.

How do I install this padlock correctly, and what step is often missed?

Insert the shackle fully until it clicks into the square hardened steel body; the non-removable key feature means the key cannot be withdrawn unless the shackle is locked, confirming full engagement.

What maintenance or replacement will this padlock need over time?

The 5 or 6 pin Yale No. 8 cylinder is rekeyable and uses an interchangeable core, so a locksmith can re-pin or swap the core instead of replacing the whole padlock.
