Quick Take

If your workspace has a laptop, a desktop PC, a printer, and a few peripherals, the decision depends on the job you need done. At $14.99, the Kensington Desktop Peripherals Locking Kit 2.0 Computer Cable Lock K67990US is the most affordable item in this group. The Tripp-Lite SEC4K is a 4-ft security lock for laptops and peripherals at $24.99. The Kensington Desktop Peripherals Kit 20 Security Lock is priced at $35.19 and is designed to secure a computer, up to three peripheral accessories, and a wired keyboard/mouse. The Eaton USB 2.0 Active A/B Cable is the highest listed price at $60.99 and is meant for printer and peripheral connections across longer distances.

What's the Right Fit?

Before comparing prices, think about the physical setup. A keyed lock works when the device has a security slot and you want a simple anchor. A desktop kit makes sense when multiple pieces sit together on or around a desk and you want one system for keeping them in place. A cable lock is a narrower tool: it locks a peripheral with a single cable, but it doesn't provide the same multi-point coverage as a kit. The USB cable is a different category entirely-it doesn't offer security but solves a distance problem. Matching the product to the situation matters more than picking a single best item, because the right choice depends on whether you're protecting equipment or extending a connection.

Product Notes

Tripp-Lite SEC4K | Security Lock for Laptops and Peripherals, Keyed, 4 ft

The Tripp-Lite SEC4K is a keyed security lock for laptops and peripherals that have a compatible security slot. Its 4-ft cable is the length listed in the title, and the product is identified as new with a one-year manufacturer warranty. If you want a single-device lock with a key rather than a separate kit, this is a direct fit. The limitation is that it focuses on one device at a time; it doesn't include the multiple connection points of the Kensington desktop kit, so you would need extra locks for additional peripherals. It also relies on the device having the expected security slot.

Kensington Desktop Peripherals Kit 20 Security Lock for PCs and Accessories

This kit is meant for a full desktop setup. It can lock down a computer and multiple peripheral accessories, making it the broadest security option in this group. If you have a desktop PC with several accessories, this kit reduces the number of individual locks you need to manage. It's listed in black, which may help it blend in with typical desk equipment. The limitation is that it's aimed at stationary PCs and their accessories rather than a portable laptop, so it's less useful if your main need is a quick lock for a single device you move around.

Kensington Desktop Peripherals Locking Kit 2.0 Computer Cable Lock K67990US

This is the most affordable option in the group, and it's described as a computer cable lock. It's a Kensington-branded locking cable rather than a keyed lock or a multi-device kit. If you want a simple way to lock one peripheral using a cable lock, this is the pick that keeps the initial cost down. The limitation is scope: it doesn't include the multi-accessory security of the Kensington Desktop Peripherals Kit 20, so you'd need additional locks if you want to secure more than one peripheral.

25-ft Eaton USB 2.0 Active A/B Cable - Perfect for Printers and Peripherals

This cable is built for distance rather than security. It includes an integrated active repeater and supports 480Mbps transfer over the full 25 feet, which addresses the usual USB distance limitation. The connectors are USB A and USB B, so it's built for devices that accept a USB B input, such as many printers and other peripherals. The limitation is that a long active cable is a specialized purchase: it doesn't lock anything down, and the USB B connector limits it to compatible devices rather than every USB device on your desk.

Final Recommendation by Use Case

Single device lock: Choose the Tripp-Lite SEC4K if you want a security lock for a laptop or peripheral with a security slot.
Desktop multi-device security: Choose the Kensington Desktop Peripherals Kit 20 if you need to secure a desktop PC and several accessories.
Simple cable lock: Choose the Kensington K67990US if you want a straightforward cable lock at the lowest listed price in this group.
Long-distance USB: Choose the Eaton USB 2.0 Active A/B Cable if you need to place a printer or peripheral far from the computer.
