ABUS Granit 37/80 Heavy Duty Hardened Steel Padlock - Closed Shackle Lock with 1/2" Shackle - Corrosion Resistant Outdoor Lock - Made in Germany - Keyed Different

This lock is heavy, solid, and one of the best I've owned. Just make sure that it will fit the application you want it for as the clasp is larger than a normal locks.

After days of research I've discovered this high quality German made ABUS 37RK80 padlock is by far the most bulletproof beast I will ever need, they were designed to lock the hatch on a tank! The body of the lock is made from high quality solid steel, the keyway is the most advanced design and 100% unpickable except by very few of the best lock smiths in the world, the shackle guard means bolt cutters can't touch it, this lock combined with a # 8 grade industrial chain will prevent any tools including cordless angle grinders from defeating this set up, if you value your bike as much as I value mine, get this lock.

Es un candado en extremo robusto. Las fotografías no le hacen justicia ni al tamaño ni al peso. Es el tipo de candado que desalienta a cualquier ladrón incluso de verlo. Vale cada peso.

This is a great, high-security padlock. Highly pick-resistant, and essentially impossible to cut the shackle with even a 42 inch bolt cutter. You will have a difficult time finding this quality lock for the same price.BUT - if you are looking for an ordinary padlock most likely this one is not for you. The price should be one indication of that.The shackle diameter and size of the opening are properly described in the Amazon information. The lock is very heavy - about 2.2 pounds, certainly not the 0.16 ounces as currently listed in the Amazon information.The lock won't fit most storage lockers, won't fit most trailer hitches, etc. It is not meant for shipping containers - that is what the RotaLok padlock was designed for.Before you purchase make sure it will work for your application. Locking up a large, heavy-duty, hardened steel security chain is one good application for this lock - and even then it will only fit around one link, so the chain needs to be a pass-through type where one link can fit through another.The lock is designed and tested to meet European security standards - and meets CEN 5. The shackle is protected on all sides, unlike some other lower-security padlocks where a part of the shackle is left unprotected.The shackle is removable and will completely come out of the lock body when padlock is unlocked. This allows for a shackle guard with complete coverage, not partial coverage as is required for most padlocks where the shackle is retained when opened. This is a security feature of the padlock. If you don't like that then this lock is not for you.The key can be removed from the lock after the shackle is removed, but only if the padlock body is relocked. This means that to replace the shackle the key must be reinserted, the body unlocked, the shackle inserted, the body locked and the key removed. This is a security requirement to meet the European CEN rating. Really not that difficult to do - but again if you don't like that feature this lock is not for you.If you just want a padlock to lock up your storage locker, trailer hitch or the like you will be better off looking elsewhere. Maybe a Master lock for $10 to $20, or a more pick-resistant American lock. If you want something more pick-resistant consider one of the smaller Abus locks - maybe the 20/80 Diskus.

One look at this lock in your hands and you will understand that this is probably the best lock you will ever own. The lock is thick, strong, extremely smooth action with the key and shackle and seemingly impenetrable. Well worth the cost to secure whatever it is you are locking up. The lock will not be the weakest link in your security, likely the hasp or whatever it is attached to is the weaker point, so get a good ABUS hasp and attach it well.
