What is a Round Disc Padlock & When Are They Best Used? 

A round disc, also known as a round padlock, is shaped like a disc hence the name. It comes with a short and curved shackle making it very tough to access the lock with basic tools and bolt cutters. 

One reason why disc locks are so popular over traditional padlocks is the locking mechanism. There isn’t any spring involved, so even when the key opening is tried to be messed with, the shackle remains closed. 

The short U-shaped shackle’s ends are connected with two metal cases. The keyhole is situated at the center for easy access.

Because these locks are mostly hollow, ABUS and several other premium brands have further improved their disc locks’ security by inserting a hardened steel disc into the casing to avoid crushing the lock case. As a result of this upgrade, ‘ABUS Diskus’ has become the leading brand in the disk lock market.

As we have mentioned earlier, disc locks are most popular for storage units. They’re almost impossible to break, cut, or damaged using power tools like bolt cutters, saw, and hammers. Almost everyone goes for a disc lock when it comes to storage unit protection. 

Even though a disc lock’s basic design features a keyed system, there are disc locks with a combination system too. Disc locks often come with a weatherproof feature so that you can also use them in any outdoor facility.

People also prefer disc locks for their garage, main gates, backyard doors, truck doors, and other similar situations. One thing about disc locks is that the short and thick shackles don’t fit all door clasps. This is one of the reasons for the limited use of disc locks.  

Other than the obvious uses, you can use them anywhere you want added security. Anywhere you can think of using a padlock is a suitable choice for a disc lock. After all, disc locks are a variation of padlocks. But the best use remains when it comes to storage safety without any argument.    

Regular Padlock vs Disc Padlock 

A disc lock is a modernized regular padlock to prevent forced entry. In terms of shackles, standard padlocks have open shackles where disc locks come with closed shackles. 

If you measure these two on a security scale, a disc lock will undoubtedly outrun a standard padlock. Some regular padlocks provide high-security. Some even can withstand bolt cutter attacks if the shackle is hardened. But traditional padlocks generally are not very good at providing you with security when it comes to strong tools like bolt cutters and hammers.   

Open shackle locks are very vulnerable to pry attacks. Disc locks will provide far better security than a regular one. They not only differ in basic structure and lock mechanism but also in security measures.

If we talk about appearance, however small this attribute may be, disc locks are better looking. The structure of a disc lock features a more contemporary look than a regular padlock. Long shackles on regular padlocks have a lot to do with this difference.   

Summarizing the differences, disc locks are better-looking, prevents pry attacks, bolt cutter attempts, lock picking, and other forced entries. In comparison, regular padlocks are more vulnerable when it comes to these attacks. 

Buying Guide To Pick The Best One For Stopping Forced Entry

What should you measure when you need the best disc padlocks? Some things matter more than others. Keep the following features in mind when shopping for your storage unit lock.

Security Level

Depending on the reasons you need the lock, security levels will vary. You’ll never buy a disc lock with extreme security for guarding something ordinary. If you need a lock for something thieves won’t bother to go through lock picking, we recommend you go for a standard padlock. But if you are buying a lock for your vehicle’s safety, important belongings, you should go for a high-quality disc lock providing the highest level of security. 


Ensuring that the shackle fits your door is a must. Sometimes users purchase their locks and end up not being able to use them. Because of the thickness of the shackle, sometimes it’s not compatible with the hasp. 

Because disc locks come with short shackles, it’s crucial that you enlighten yourself about the measurement. Read through the manufacturer’s description of the lock and match them with your storage unit. If you don’t get any information from the description, you can always ask the manufacturer about it. 

Number of Pins

The more pins a lock has inside it, the more difficult it will be to pick. We recommend you at least go for the locks that have a minimum 5 pins. With the increased number of pins, you will get increased security. Some locks come with 7 to 10 pins that are extremely difficult to pick. 

If you want your lock to be almost immune to picking, choose the one with a larger number of pins inside. 

The pins are aligned in a particular placed when a key is inserted and turned. Unless the pins align, the lock cannot be opened. More means require more time to pick without keys.

Lock Built

The body should be made of high-quality metals. Making the locking mechanism hard to pick and then using cheap materials doesn’t bring anything new to the table. When a lock is well-built with a robust structure, it will be difficult to break even with strong tools. 

Hardened materials are most suitable for making a lock strong and immune to breaking tools like bolt cutters, saw, and hammers. 

Weatherproof Feature

The lock must be immune to weather damages like rust, dirt, moisture, etc. Imagine your lock getting rusted when exposed to rain and breaking down eventually. A good disc lock will be immune to these situations and withstand attacks with the same strength in all weather. 


When you are choosing the best materials, durability comes without asking. Still, it’s important that you choose something that’ll remove the frequency of buying locks. If you needed to change a lock after one or two months, that probably wasn’t the best lock for you anyway.

Also, look for a weatherproof and corrosion-resistance feature in the lock. The best lock for the storage unit will be difficult to pick and immune to bolt cutters, saw, and hammers.

  • How To Measure Storage Unit Lock?

Storage unit locks are measured by their width. The most common sizes among storage unit locks are 1 3/4, 2, and 2 3/4. Any lock larger than 2 3/4 will not be likely to fit on the door latch. Remember that the smaller the lock is, the easier it is for someone to access it without authority. 

  • Why are locks in storage units important?

The elementary intention of storage units is to provide security. It’s essential that your property stay safe. This is why you must make sure that you’re enforcing everything from your side. Locks make sure that your belongings stay safe in storage units from unwanted attacks. 

  • How to Choose a Lock for Your Self-Storage Unit?

When shopping for your self-storage unit, look for the locks largest in size yet fit the door latch. The bigger the lock is, the more difficult it will be to pick, break or cut the lock.  

  • Which type of lock is the hardest to pick?

Different factors make a lock difficult to pick. The locking mechanism, number of pins in the lock, shackle type are some of the factors. Hard-to-pick locks will feature a complex locking mechanism, 7 to 10 pins, and a closed shackle. 

  • What if you misplace your keys a lot?

It’s better to purchase locks with removable cylinders or alterable pins. If you misplace your keys and the keys fall into the wrong hands, your security will be at stake. Change the locks as soon as possible after misplacing your keys. 


Bottom Line
