Master Lock 1177 ProSeries® – The Shrouded Shield for High-Risk Sites

At Aus Lock and Safe Co, we’ve seen that even the toughest locks have a "weak neck" where bolt cutters can gain purchase. The Master Lock 1177 ProSeries® is the answer to that vulnerability. By taking the proven brass body of the 1175 and extending the body upwards to form a shrouded shackle, Master Lock has created a combination lock that is nearly impossible to cut or pry.

This is the ultimate "set-your-own" solution for Melbourne’s utility substations, remote storage units, and industrial yards where you need maximum cut resistance without the logistical burden of managing hundreds of physical keys.

Why Choose Aus Lock and Safe Co?

High-security combination locks are a strategic investment. At Aus Lock and Safe Co, we help you manage that investment across your entire operation.

1. Site Security Strategy: We can help you determine which areas of your facility require the shrouded 1177 for perimeter gates and where the standard 1175 might be sufficient for internal lockers.

2. Code Management Protocols: For our commercial clients in Laverton North and beyond, we provide guidance on setting up secure code rotation schedules to ensure your security remains uncompromised as contractors change.

3. Industrial Asset Protection: We don't just sell locks; we sell peace of mind. We ensure your hasps and gate hardware are strong enough to match the SP-rated strength of the 1177.

Pro Tip: The shrouded shackle on the 1177 is quite thick (10mm). Before ordering, ensure that your gate hasp or chain links have at least an 11mm or 12mm opening. A snug fit with a shrouded lock is ideal, as it leaves zero room for a thief to insert a grinder blade or pry bar.
