Master Lock Padlock KA 2 In H 4 Pin Steel

Weather-Resistant Steel Padlock

The Master Lock padlock uses a laminated steel body and a 3/8-inch steel shackle to resist cutting and prying. Its weather-resistant construction protects the internal mechanism from rain, dust and corrosion, making it suitable for outdoor gates, sheds and storage units. The four-pin cylinder is keyed alike to number 3210, so multiple locks open with the same key. This design serves homeowners and small-business owners who need reliable keyed-alike security for exterior applications.

Upgrade from Basic Single-Lock Sets

Replacing individual keyed-different padlocks with this keyed-alike model eliminates the hassle of managing separate keys for every access point. The jump is worth it when you operate several gates, toolboxes or locker doors and want one key to open them all without a master-key system. It is not for buyers who need unique keys per lock, rekeyable cylinders or interchangeable-core flexibility for future changes.

Sustained Outdoor Exposure

The laminated steel body and weather-resistant finish maintain function through repeated rain, humidity and temperature swings without the binding that affects non-sealed locks. The four-pin cylinder continues to turn smoothly after prolonged exposure, reducing the risk of a stuck shackle when you need quick access. It is not for high-security requirements that demand hardened shackles, anti-drill plates or higher pin counts.
