Disc Lock vs. Regular Padlock: What’s the Difference & Why It Matters

When you rent a storage unit at Back Forty Storage, one of the most important decisions you make is how you choose to secure it. While any lock is better than none, not all locks provide equal protection—and when it comes to safeguarding your valuable property, the type of lock you choose makes a major difference.

Below, we break down the key differences between disc locks and standard padlocks, and why we highly recommend choosing a disc lock for your unit.


🔒 What Is a Disc Lock?

Disc locks are designed specifically for storage units. Their round shape and shielded shackle make them extremely resistant to cutting and prying.

Key Features:

  • Hardened steel construction

  • Short, shielded shackle that makes bolt cutting extremely difficult

  • Resistant to tampering and picking

  • Designed to fit storage unit latches securely


🔓 What Is a Standard Padlock?

Padlocks are the more traditional type of lock commonly used on gates, garages, and toolboxes. While convenient, they often have exposed shackles that are easier for thieves to cut.

Common Weaknesses:

  • Exposed shackle can be quickly cut with bolt cutters

  • Easier to pry open

  • More susceptible to lock picking

  • Not designed with storage-unit–level security in mind


🔐 Why Disc Locks Are Superior for Storage Units

When it comes to protecting your belongings inside a storage facility, disc locks outperform padlocks in every category.

1. Far More Resistant to Cutting

The design of a disc lock shields nearly the entire shackle, leaving very little room for bolt cutters to grip. Standard padlocks, by comparison, have large exposed shackles that can be cut in seconds.

2. Harder to Pry Open

A disc lock sits snugly against the storage unit latch, making it extremely difficult for thieves to insert tools to pry it open.

3. Built Specifically for Storage Doors

Disc locks align perfectly with roll-up unit latches and offer the highest level of security recommended by most storage professionals.
