MASTER LOCK ProSeries 1177D Combination Padlock Closed Shackle 57mm Brass Body

The Master Lock ProSeries 1177D is a heavy-duty, resettable combination padlock designed specifically for demanding commercial and industrial environments. Featuring a robust 57mm solid brass body, it offers outstanding corrosion resistance, making it ideal for tough outdoor applications.

Security is at the forefront of the 1177D's design. It features a closed shackle (shrouded) body that shields the 10mm octagonal boron-carbide shackle from cut, crop, and saw attacks. Furthermore, a built-in deadlocking mechanism provides exceptional resistance against prying, shimming, and rap attacks.

This padlock features a user-resettable 4-digit combination mechanism, offering 10,000 possible combinations with no reset tool required to change the code. For reliable operation in harsh conditions, it includes a shackle seal and dial dust cover to protect the internal components from dirt and moisture. Additionally, the innovative 'blind dial' feature allows you to operate the dials easily while wearing gloves or in low-light and complete darkness.
