Here's an easy and economical way to secure accessories to your main lock cable. This laptop cable lock expansion loop works with your base laptop lock, to add a 6" (2.5 cm) extension cable and lock-head that connects into devices with the Kensington K-Slot. The expansion loop with a K-slot lock head makes an ideal accessory to loop around any type of main cable lock - including a K-slot, nano or Noble Wedgelock letting you easily secure a variety of devices. Now if you have a single laptop lock, you can protect more devices like your docking station or monitor. This lock accessory works like a dual-head or twin laptop lock to secure additional devices with ease. You can even use multiple laptop lock expansion loops to protect devices on your desk, or on display, while taking up little space. It's the ideal way to help prevent theft and tampering in areas with high foot traffic including retail, commercial, educational and institutional environments. Choose your own combination so you can remember it easily. Or, change your passcode often to prevent others from knowing it. To ensure that your dock, tablet or other device is anchored safely, the computer security cable features a vinyl-coated steel cable (4.4 mm diameter). The laptop lock add-on features a durable zinc-alloy lock head, to provide dependable theft protection.
