Master Lock Combination Padlock Brass 4-Digit Long Shackle — Weather-Ready Security for Gates & Sheds

The Master Lock 175DLH is a weather-ready, set-your-own 4-digit combination padlock with a long hardened-steel shackle for flexible outdoor use.

Designed for gates, sheds, storage boxes and other exterior needs, this Master Lock model pairs a solid 2-inch brass body with a 2-1/4-inch long, 5/16-inch diameter hardened steel shackle to resist cutting and provide extra reach for awkward hasps and chains. The four-digit dial gives thousands of possible codes so you can choose a memorable combination; the lock ships preset to 0-0-0-0 and includes the tool and instructions to change it. Backed by Master Lock’s limited lifetime warranty, the 175DLH balances durability, convenience and straightforward security for everyday outdoor applications.

How secure is the 175DLH against cutting and weather exposure?

The lock combines a solid brass body that handles corrosion with a hardened steel shackle sized to resist common cutting tools. While no padlock is invulnerable, the materials and construction provide a robust deterrent for typical theft attempts and many outdoor environments.

• Solid 2 in (51 mm) brass body for corrosion resistance.
• 5/16 in (8 mm) hardened steel shackle for improved cut resistance.
• Shackle length 2-1/4 in (57 mm) gives extra clearance for fittings.
• Designed for indoor/outdoor use — suitable for gates and sheds.

How do I set and change the four-digit combination?

Changing the code is straightforward using the included combination-change tool and the printed instructions. The lock ships preset to 0-0-0-0 so you can use it immediately and then switch to a personalized code when ready.

• Preset to 0-0-0-0 for immediate use out of the box.
• Includes reset tool and step-by-step instructions in the package.
• Four dials offer 10,000 possible numeric combinations to choose from.
• Keep your chosen code memorable but not easily guessed by others.

Will the 175DLH fit my gate, shed or storage hasp?

The long shackle increases compatibility with thicker or offset hasps, chains and fittings, but you should measure your application beforehand to ensure the shackle and body clearances match. The product dimensions are listed for quick verification.

• Body width: 2 in (51 mm) for compact but sturdy profile.
• Shackle: 5/16 in (8 mm) diameter, 2-1/4 in (57 mm) length for extra reach.
• Recommended for gates, sheds, storage lockers and chains where additional shackle length is needed.
• Measure backset, cross bore and thickness of your latch before purchase.

What kind of warranty and support does Master Lock provide?

The 175DLH includes Master Lock’s limited lifetime warranty, giving you support for defects in materials or workmanship under normal use. Documentation and user-support resources are available from Master Lock for combination reset guidance and general product questions.

• Limited lifetime warranty from Master Lock for covered defects.

Who is this for: The Master Lock 175DLH is a practical choice for homeowners, renters and small-business users who need a reliable, no-key security solution for outdoor fittings that require extra shackle length. It’s especially helpful when you want a corrosion-tolerant brass body, the convenience of a changeable numeric code, and a shackle that clears bulkier hasps or chains without needing a separate keyed lock.
