I’m looking for a good option to lock a metal gate. This is in a developing country where theft and burglary are very common, so properties are surrounded by tall walls or fences with vertical metal bars. The lock on the entry gate is probably the weakest link, and locally-sold options are pretty low quality locks, so I’m planning to get something shipped from the US to install.
I’d imagine a deadbolt in a box welded to the gate would be the best option? The real risk is probably a physical attack, so I’d like something that isn’t going to come apart with minimal effort if someone takes a hammer or pry bar to it. It’s also outside, so it needs to be fine in heavy rain. It would be great to be somewhat pick resistant and not able to easily rake, but the physical qualities are the most important.
I’ve seen recommendations for the Schlage B560 or B660 (maybe changing the bitting or adding security pins for a bit of extra security), which seem great for traditional use cases, but I’m not sure if those would handle being outside and how their physical resistance is. Any recommendations on good options to look into?
