What the Master Lock 176 is

The Master Lock 176 is a 51mm solid brass combination padlock with a hardened steel shackle designed for outdoor and indoor security. It offers a set-your-own four-digit combination plus a key override for supervisor or emergency access. The 4-pin tumbler cylinder helps resist picking while the weather-resistant finish protects against corrosion. This padlock suits gates, sheds, lockers and storage units needing reliable keyless entry.

Check before you order

Verify that the 51mm body width matches the hasp or mounting hardware you plan to use. Ensure the shackle diameter and internal clearance fit your chain, gate latch or locker loop without forcing. Confirm you want a key override feature and can store the override key securely. No batteries or electronic components are involved, so no power source is required for operation.

Who this suits and who should look elsewhere

This padlock suits users who want a resettable combination with a physical key backup for shared or supervised access. It is not for buyers who need a higher-security rating such as a shrouded shackle or a lock rated for heavy-duty industrial cutting resistance. It is also not for those who require a digital keypad, Bluetooth connectivity or an audit trail of openings.
