Master Lock 1175 ProSeries® – The Commercial-Grade Combination Workhorse
At Aus Lock and Safe Co, we often see combination locks fail when exposed to the grit and rain of a Melbourne construction site. The Master Lock 1175 ProSeries® is designed specifically to solve that problem. This isn't your standard school locker lock; it’s a heavy-duty, resettable padlock built for industrial environments where security is critical, and physical keys are a liability.
The 1175 is the go-to choice for utility substations, storefront gates, and manufacturing sites across the West. It combines the ease of a set-your-own 4-digit code with the brute strength of a high-security mechanical deadlatch.

Details
- Locking Mechanism: Combination
Features & Benefits
- Octagonal Boron-Carbide Shackle: The shackle is crafted from a specialized boron-carbide alloy that is twice as hard to cut as standard hardened steel. The patented octagonal shape makes it incredibly difficult for bolt cutters to get a firm grip.
- Deadlocking Mechanism: Unlike cheaper combination locks that can be "shimmed" open with a piece of metal, the 1175 features a deadlocking mechanism that protects against prying, shimming, and rap attacks.
- Superior Weather Protection: Built for the elements, it features a solid brass body for maximum corrosion resistance, along with a rubber shackle seal and a hinged dial cover to keep dust and moisture out of the internal gears.
- Blind Dial Feature: The large, ergonomic dials are designed to "stop at zero." This allows you to operate the lock in complete darkness or while wearing heavy work gloves by simply counting the clicks.
- 10,000 Possible Combinations: Set and reset your own 4-digit code as often as needed—no special reset tool required.
- ProSeries® Durability: Engineered for high-frequency commercial use, the internal components are reinforced to handle thousands of cycles without sticking or jamming.
