4-Digit Cable TSA Luggage Locks: Maximum Security and Ultimate Flexibility

Not all travel security measures can be met by a standard travel security solution. In the case of the adventure-packed traveler, the photographer, or the world traveler with valuables, 3 digits are simply not sufficient. This is exactly why 4-digit cable locks from Forge were designed to fill the void between heavy-duty security and versatility.

With our Wyoming workshop through airports around the globe, Forge provides protection you can count on. In our line of travel locks, while meeting TSA requirements, our products go beyond the needs of traveling by providing features such as 10,000 combinations and tamper evidence.

Why Upgrade to a Forge 4-Digit Cable Lock?

A typical traveler will make due with common locks that one can purchase from airport kiosks. Those who consider securing their belongings important will appreciate what the 4-digit series has to offer.

10x More Secure: The Power of 4 Digits

Adding a fourth dial exponentially multiplies the difficulty of cracking the combination lock. A four number combination lock gives a total of 10,000 combinations, thereby making it ten times more secure to crack. This variant is always preferred for securing guns, high-end cameras, and important documents.

“Fits Everything" Cable Design

Hard-shell restraints work well, but they will not function well with modern zipper pulls, which is a problem that Forge eliminates by using a braided cable made of steel coated with vinyl.

  • Universal Fit: The thin, flexible cable is able to go through the smallest zipper holes on backpacks and duffel bags, thus making them the best locks for backpacks.
  • Hard Case Ready: Specifically designed for Pelican cases or gun cases in which locking points are either recessed or too small in width for a regular shackle.
  • Impact Resistant: Our cable can absorb impact and bend without breaking, whereas rigid shackles are likely to break under leverage.

Know If You’ve Been Searched: Open Alert Indicator

Privacy is something that matters. That’s why certain styles in our collection include our signature Open Alert Indicator. When the TSA representative decides to check your bag with his or her master key, an indication in the form of a red flag will pop up on the lock. This means that as soon as you collect your bag, you will know whether it has been opened or not.

Built for the "Gear Heavy" Traveler

Our 4-digit cable locks are developed for particular user audiences for whom failure is never acceptable.

For Photographers & Professionals

When you are investing in lenses and bodies worth thousands of dollars, you will need a cable lock for luggage that is compatible with hard cases that are designed to protect your equipment. The lock comes with a 4-digit security system, guaranteeing that you are protected, while the TSA008 cylinder, which comes with some versions, is state-of-the-art when it comes to security locks.

For Backpackers And Hostel Hoppers

But security doesn’t end at the airport. These combination locks are a dual-use product for backpackers on a budget. They can be used to secure your pack’s zippers during travel and then used with the cable to secure your pack to a hostel bed frame or locker. The cable lock can lock in awkward positions, which is impossible with rigid locks.

For Families & Groups

When it comes to family vacations, organizing the baggage can sometimes be nightmarish. The fact is that you can get locks in 2-pack or 4-pack sets so that the entire family’s baggage gets locked with one purchase. Having the same 4-digit code for all family members means that you do not have to worry about whose code is whose.

Frequently Asked Questions about 23072 4 Digit Cable

Why would I prefer using the cable lock over the rigid shackle lock?

The key benefit is the flexibility of the cable lock that allows the user to secure the luggage through the use of the zipper pulls and any other locking points that the hard case lock cannot reach because of the rigidity of the shackles. In addition, they are resistant to being damaged by the levering action of the conveyor belts.

How do I set the combination on my 4-digit lock?

It is very simple to set your code. While the lock is in the open position (which is 0-0-0-0), simply use the tip of your pen to press the reset button, usually found on the bottom or side of the lock, and then enter your desired 4-digit combination by not releasing the reset button.

Is a 4-digit lock really more secure than a 3-digit lock?

Yes. In a combination luggage lock with 3 digits, a total of 1,000 combinations could be bruteforced in 10-20 minutes. However, with a 4-digit lock with a total of 10,000 combinations, hours will be needed to break into the luggage.

Is this lock suitable for use on a Pelican or gun case?

Yes. The steel cable has a thin thickness that can pass easily through the reinforced holes of any high quality locking case brand like Pelican, Storm, and Nanuk. In fact, steel cable locks like this one are common on gun cases going on aeroplane journeys because they conform to TSA standards.

What is meant by “Open Alert”?

It is actually a security feature found in our upgraded versions. A red dot or indicator will appear in the lock whenever it has been opened by the master key possessed by the TSA, signaling that your luggage has already been checked.
