Weather Resistant

Manufacturer Guarantee
The Squire All Terrain Brass Padlock range (ATL42S and ATL52S) is engineered for environments where weather resistance is just as important as security. Built around a solid brass body and protected by an all-weather polymer coating, these padlocks offer excellent resistance to rain, dirt, and exposure.
Each model uses a stainless steel shackle, chosen not for maximum cutting resistance, but for unrivalled corrosion protection. With a 6mm diameter on the ATL42S and a robust 8.8mm diameter on the ATL52S, both versions remain tough enough to deter opportunistic attacks while offering long-term reliability in demanding conditions.
A double-bolted locking mechanism means that even if the shackle is cut once, it must be cut again to remove the lock, significantly slowing forced entry attempts. For users who need dependable outdoor security without the weight or cost of high-security, hardened-steel models, the All Terrain series is an ideal fit.
