Review: Shipping container lock - Very heavy duty lock. Works great securing my shipping container. Time will tell how well it stands up to the elements.
Review: Heavy duty lock with a thick shackle so your lock doesn't become the weakest link! - This thing is stout! I was looking for a lock that would fit three 5/8" steel braided cables. This one works perfectly (see photo) and the actual "shackle" is thick like the cables themselves. I didn't want to put a weaker lock around the cables because then it's much easier to just cut the lock than the cables. With this lock I'm confident that cutting either the lock or the cables will be tough. Not only is it very sturdy but the design also allows the shackle to freely rotate when it is locked. This makes it even more difficult to use a saw or some other device against it since the shackle will spin. The lock is very heavy and also has the added bonus of coming with five keys.

## Features

- HEAVY DUTY STEEL LOCK: This lock is made of hardened steel to keep your contents safe and the bad guys out. The lock weighs a heavy 850g and measures L10 x W2.4 x H6.5cm (3.94 x 0.94 x 2.56 inches). The shackle measures 12 mm in diameter. When locked the gap measures L3.9cm x H2cm (1.54 x 0.79 inches). This makes this padlock the perfect size for most latches.
- ULTIMATE SECURITY: Weighing at a mighty 850g this lock is super tough. With its hardened, solid steel body it makes it high strength and extremely durable. It has a rotating shackle/closed shackle making this lock anti-drill and anti-saw. The lock has been designed with security in mind leaving no weak spots.
- 4 KEYS INCLUDED: All of the padlocks sold come with 4 keys. You can never have enough spares. Keep a few in a safe place so you are covered if you lose one. With 4 keys, you will have enough to give to close friends and family members. Keys can only be removed from the lock when it is in the locked position.
- LOCKUP AND LEAVE: Given the unique D shape of the lock it makes it the perfect solution for securing industrial 20ft or 40ft containers as well as gates, garage doors, caravans and storage units. Also being very sturdy the lock can be used when locking up the chain on your motorbikes.
- DESIGNED FOR LIFE: Every product in our collection is built with purpose, blending function and style. Our thoughtfully crafted designs ensure lasting reliability and convenience when needed, ideal for any occasion.

### ⭐⭐⭐⭐⭐ I bot 2 of these for outdoor use. Years later, no problems.
*by S***Y on March 7, 2021*

They are not rusted and they always pop open. The paint looks almost new. Where I live, Top notch, "Locksports", do not come out at night, stealing well used garden equipment. Parolees and drug addicts come out stealing, as soon as it gets dark. Years later, no problems. Key does not come out, until you resecure the lock. Helps keep the key from getting lost.
