As an accessory to our desktop and peripherals locking kits (K64615US and K64424WW), the Locking Eyelet for Standard Slots is an excellent solution for securing laptops or desktop peripherals because of its unique barrel design. The robust barrel cylinder rotates 360-degrees for maximum flexibility when the security cable is installed. Takes seconds to attach or detach using the included allen wrench. Five-year warranty. From Kensington, inventor of the laptop cable lock, and industry leader in physical device security for more than 25 years.
