Master Lock M175XDLF Heavy Duty Outdoor Combination Padlock | Weatherproof & Resettable 4-Digit

Rugged durability for outdoor security

The Master Lock Magnum M175XDLF is built to endure exterior spaces where security and weather resistance matter. A 2-inch-wide zinc body communicates strength at a glance, while a 3/8-inch (10 mm) boron-carbide shackle—1-1/2 inches long—offers a material edge over standard hardened steel. A roller pin cylinder adds another layer of defense against common lock-picking methods. The hinged dial cover and shackle seal help shield the mechanism from rain, dust, and spray, and a reinforced body bumper cushions daily handling to resist scratches. With a four-digit, resettable combination, you can change access codes quickly without needing a reset tool. Master Lock backs this model with a Lifetime Guarantee, underscoring a long-standing commitment to outdoor reliability without promising outcomes in every scenario.

Designed for practical outdoor use, this padlock shines where gate, shed, or storage security is needed. It balances robust construction with straightforward operation, letting you manage access with a code you choose and remember. The combination of a weatherproof shield, a high-strength shackle, and a secure cylinder creates a credible option for protecting tools, equipment, or outdoor valuables across seasons and weather conditions.

Weather-ready design

• Shackle seal and hinged dial cover protect the mechanism from rain, dust, and spray.
• Reinforced body bumper guards against scratches and bumps during daily handling.
• Extended shackle offers installation flexibility with various hasps and mounting configurations.
• Tough-Cut boron-carbide shackle is 50% harder than hardened steel for enhanced resistance to cutting and prying.

Security and convenience you can count on

• Set-your-own four-digit combination for easy recall with no reset tool required.
• Roller pin cylinder design boosts resistance to picking and prying attempts.
• 2-1/4 inch (57 mm) wide lock body provides substantial durability for outdoor installations while remaining user-friendly to operate.

Use cases include securing a backyard gate, a garden shed, or outdoor storage units. While outcomes depend on the right fit and installation context, the model’s weather protection, durable shackle, and high-security components offer a practical option for multiple outdoor sites. If you manage several access points, the resettable code adds flexibility across seasons and occupancy changes.

Choosing the right fit

Before selecting, measure your door or gate’s backset, cross bore, and thickness to ensure compatibility with the 2-1/4 inch (57 mm) body and the extended shackle. The extended shackle provides installation flexibility, but verify it clears surrounding hardware.
