We have three long shackle padlocks on our beach hut and someone has tried to cut through one of them. Luckily they didn’t get in but we have decided to change them for closed shackle ones to make it as hard as possible. As the hut is right on the coast we need the padlocks to stand up to the seaside weather. Although we want something more secure then before we do not want it too look so expensive they end up going through the wall of the beach hut as the easier option. We are thinking that a big chunky padlock may lead them to think there is more to steal then there really is.

There are a number of options you could use and given the dimension of your existing fittings I would start with a look at the Abus 24IB/60 Diskus. This fully marine grade padlock is ideal by the coast and comes with 360 degree anti-cut protection in the reinforced body. Giving you the increased security you are looking for without the chunky look of the larger high security padlocks. It also comes in a keyed alike version so that you can use one key to open all three padlocks, which will save you having to work your way through a bunch of keys. This particular size has an 8mm shackle which you already know is suitable with your current fittings. Once in place then access to the shackle is limited so makes it a lot more difficult to get bolt croppers or hacksaw in to cut it. The padlock design means the shackle cannot retract into the body without the use of the key, so this means that two cuts to the shackle would be required in order to remove it.

If you find that once fitted to your beach hut that there is still some shackle on show due to your fittings, then you could add a bolt nut to help fill the gap. This would reduce the amount of shackle that is exposed and make it harder to access with cutters. Although this can reduce the risk of hacksaw attacks, this rememdy cannot be used on all padlocks since it can act as leverage for bolt crop attacks. For these particular padlocks you would be fine to add the bolt nut if you wished. For anyone not sure whether to add the bolt nut or not, then a quick read of the article on making a standard padlock more secure will help you decide.
