Multplx Universal Laptop Security Lock 1.7m Cable

Multplx Universal Laptop Security Lock is a cable-and-anchor system that secures laptops and tablets without a Kensington slot by using the 3.5mm audio port, a cut‑resistant 1.7m steel cable, and a resettable 4‑digit combination lock.

This compact anti‑theft kit gives you a fast, non-invasive way to tether notebooks, MacBooks, Surface devices and more to desks or fixtures where a dedicated lock slot doesn’t exist. It installs in seconds by inserting the included anchor adapter into the headphone/AUX port, then attaching the combination lock head to the adapter and looping the cable to a fixed point. Designed for everyday use in offices, coffee shops, retail counters and at home, the Multplx lock balances portability, strength and convenience without permanent modification to your device.

How does this lock attach to laptops that lack a Kensington slot?

Instead of a keyed anchor, the Multplx system uses a slim anchor adapter that fits the 3.5mm audio port common on many laptops and tablets. The adapter expands once inserted and secures inside the port, creating a dedicated anchor point for the cable and lock head.

• Anchor adapter installs via a simple screw mechanism into 3.5mm headphone/AUX ports.
• No drilling or permanent changes required to your device.
• Works with MacBooks, Surface, Dell, Lenovo and many tablets and phones with a 3.5mm port.

What makes the cable and lock durable enough for everyday anti‑theft use?

The cable is made from braided, cut‑resistant steel that resists common pry and shear attempts. At 1.7 metres long the cable offers enough reach to secure devices to desks, poles or display fixtures while still being manageable for transport and cable routing.

• Cut resistant steel braid minimizes risk of quick snip theft.
• 1.7m length provides flexible anchoring without excess slack.
• Durable outer coating resists kinks, abrasion and weathering.

How does the 4‑digit combination lock work and is it easy to use?

The lock uses a resettable 4‑digit code offering up to 10,000 permutations so you can set a private combination without keys. A quick flick mechanism allows fast locking and unlocking while still delivering a reliable mechanical hold.

• Resettable 4‑digit combination for customizable security.
• Fast flick switch to lock and release in seconds.
• No keys to lose—change code when needed for shared devices.

Where can I use this lock and which devices are compatible?

This system is designed for broad applicability: office workstations, retail displays, showrooms, classrooms, cafes and home setups. It’s compatible with any laptop, tablet or smartphone that has a standard 3.5mm audio jack; it also works as a general tether for other small items where a secure cable anchor is useful.

• Compatible with MacBooks, Microsoft Surface, Dell, Lenovo, and many tablets/phones.
• Ideal for point‑of‑sale displays, trade show booths, libraries and shared workspaces.
• Quick install and removal make it suitable for temporary or permanent setups.

Who is this for? The Multplx Universal Laptop Security Lock is aimed at anyone who needs a practical, non‑destructive security solution for devices without a Kensington slot—small business owners, retail staff, educators, students, frequent travelers and remote workers who want quick, reliable protection. If you need to secure a laptop or tablet in public or semi‑public spaces without carrying bulky restraints or worrying about lost keys, this compact anchor-and-cable system offers a simple, portable layer of deterrence and peace of mind.
