About this product

The Master Lock 1178D ProSeries padlock is a heavy-duty combination lock designed for securing tools, equipment and storage on construction sites, workshops and commercial premises. It has a die-cast zinc body and an octagonal boron carbide alloy shackle, giving strong resistance to cutting and forced removal. The resettable 4-digit combination offers over 10,000 possible codes, removing the need for key management. A deadlocking mechanism guards against prying, shimming and rap attacks, while Master Lock's blind dial system makes the combination easy to set even when wearing gloves or in poor light. A shackle seal and combination dial dust cover protect internal components from dirt, debris and moisture. Body dimensions are 57 x 50mm, 31mm thick, with a shackle measuring 24 x 27mm and 10mm thick.
