Aijmguo Laptop Lock 6.6ft Anti-Theft Cable for 3×7mm Slots

This Aijmguo 4-pack laptop lock is a keyed, heavy-duty 6.6ft cable system that secures notebooks and tablets with a 3×7mm T-bar slot.

Whether you work in shared offices, study at libraries, or travel with devices, a compact keyed lock can deter opportunistic theft and add a reliable layer of physical protection. The Aijmguo set includes four identical zinc-alloy lock heads with keys and 6.6-foot reinforced steel cables finished in silver; each lock is built to fit the common 3×7mm laptop security hole used by Lenovo, Asus, Acer, Samsung and many other notebook brands.

How does this lock secure my laptop while I’m away?

Setup is fast: loop the cable around a fixed object, insert the T-bar lock into your device’s 3×7mm slot, and turn the key. The long steel cable allows you to anchor your laptop to desks, railings, or immovable fixtures without strain.

• 6.6 ft (2 m) reinforced steel cable resists cutting and offers wide anchoring options
• Zinc-alloy lock head with keyed mechanism for simple, reliable locking
• Compatible with any device that has a 3×7mm T-bar security slot

Will it fit my specific laptop model?

This lock is designed for the standardized 3×7mm T-bar slot found on many notebooks and some tablets. If your device has that lock hole it will be compatible; models from Lenovo, Acer, Asus and Samsung commonly use this format.

• Fits laptops and docking stations with a 3×7mm security slot
• Not suitable for laptops without a security slot or with proprietary locking systems
• Four identical locks included — ideal for multiple devices or backups

How durable and secure is the cable and lock head?

The Aijmguo cable is reinforced with braided steel and the lock head uses zinc alloy, giving strong resistance to common tampering. While no lock is impervious to a determined attacker with power tools, this lock provides effective deterrence against casual thieves and quick grab attempts.

• Reinforced steel cable for cut resistance and longevity
• Zinc-alloy lock head resists prying and weather exposure
• Water-resistant finish for everyday indoor and light outdoor use

How portable and easy to store is the lock when not in use?

The cable lock is lightweight and rolls up compactly for transport. Each unit weighs only a fraction of a pound and can be stored in a bag, drawer, or the included small storage space, making it convenient for commuters and frequent travelers.

• Compact roll-up design fits in backpacks and laptop bags
• Weighs about 0.1 pounds per cable — minimal carry weight
• Four-lock pack provides spares or multi-device coverage without bulk

Who is this for? The Aijmguo 4Pack Laptop Lock is for students, remote workers, office employees, and travelers who want a straightforward keyed locking solution for devices that include a 3×7mm security slot. It’s especially useful for people managing several devices at once — the four-lock set covers multiple laptops or provides spare locks for shared workspaces. If you need a simple, portable and durable physical deterrent to reduce the risk of opportunistic theft, this set offers a cost-effective and easy-to-use option. Note: check your laptop for a 3×7mm T-bar slot before purchasing; this product does not replace biometric or electronic tracking security systems.
