  • Solid brass body resists corrosion for outdoor use

  • Standard shackle dimensions suit common hasps and chains

Solid brass body

The Master Lock 4130 padlock uses a rectangular brass body that resists corrosion and suits outdoor gates, sheds or lockers. Its 3-pin cylinder provides basic deterrence for low-risk applications. The keyed-different configuration means each lock opens only with its own key, simplifying key management for single-entry points.

Standard steel shackle

A 3/16 in diameter steel shackle with 9/16 in clearance fits common hasps and chain links without modification. The weather-resistant finish protects the mechanism from rain and humidity, so the lock remains operable through seasonal changes. No removable core or control-key registration is required, keeping installation straightforward.

Sustained outdoor exposure

Brass construction and a weather-resistant rating allow the lock to endure prolonged moisture and temperature swings without seizing. The 3-pin mechanism maintains consistent operation over repeated cycles, avoiding the stiffness that can develop in lower-grade cylinders. It is not intended for high-security needs or environments requiring hardened shackles or pick-resistant internals.

Questions about this item

How does the 3-pin cylinder hold up to daily picking attempts?

The lock uses a standard 3-pin tumbler mechanism that provides basic resistance to casual manipulation but is not rated for high-security applications.

Does the brass body and steel shackle show corrosion when left outdoors year-round?

The solid brass body and hardened steel shackle are weather resistant, so they withstand rain and humidity without rusting under normal outdoor exposure.

Will this padlock work with my existing Master Lock 4130WWG keying system?

This unit is keyed different and does not support interchangeable cores, so it cannot be matched to an existing 4130WWG keyed-alike or master-keyed system.
