About this product
A bit of history
Henry Squire has been making locks for many generations in England and they can track their heritage back to around 240 years. Amazingly, they still make some of their locks in the UK which includes these Stronghold types. Nowadays, that doesn't necessarily mean superior quality but from what we can see the quality is excellent, the working conditions at their facility is excellent and the values of the business are also great.
About this lock
This closed shackle padlock is part of their Stronghold Range and has the highest possible security rating and tested to a CEN grade of 6. For more information on these test grades please see our CEN insurance page. It has the maximum protection available against force attacks using bolt cutters, hack saws and hammers.
The body is made from hardened steel electophoretically coats to provide excellent resistance to the weather. These locks have been tested in an environment chamber to simulate over 5 years of outdoor use. Please note however this is not a marine grade padlock and not made with 316 stainless steel and we wouldn't recommend it in a salt water / saline environment. Please see our weatherproof range for these.
You'll notice that all three sizes have CEN 6 which can tbe confusing. Why buy the more expensive one when the smaller one is just as strong? Well that is only because the grade doesn't go above 6. Clearly the larger version is going to be a lot stronger than the smaller ones but by how much is hard to say.
Keys & lock mechanism
The entire base of the lock is covered by a rubber guard which folds back. This protects from water and road salt getting kicked up into the lock when hanging downwards. These locks are key retaining which means when you open the lock, the key is fixed and you need to lock it again to remove the key. The keys are a 6 pin mechanism. Each padlock comes with 2 keys included.
IMPORTANT: Note that the larger of the locks, the 100 Series, has two keys to opperate it, whilst the 65 and the 80, only use 1 key!

Uses & Applications:
Many insurance companies require padlocks which are of a CEN Grade of 4 or higher. This padlock affords a rating of 6 and is suitable for almost all insurance company requirements. To be honest CEN6 is more than most people will need but with the advent of cordless grinders with diamond blades then frankly, the bigger the better! Take a look at the video here when some Americans try shooting the Stronghold locks with one of the most powerful riffles available. Enough said.
