It features a 16mm steel bolt and an ABUS X Plus cylinder, offering high resistance to manipulation. One of its standout features is the alarm system, which emits a loud 100dB alarm when tampered with, providing an additional deterrent against thieves. The lock also includes acoustic signals to inform users about battery status, activation, and alarm status, which adds to its user-friendliness.

It comes with two keys and an ABUS Code Card for easy key replacement if needed, along with a protective bag and a CR2 battery for the alarm function. This lock is quite heavy, weighing 2.64 lbs (1.2 kg), which can affect portability. However, its weight contributes to its sturdiness. The lock's dimensions are 11.81 x 7.87 x 7.87 inches, making it relatively bulky. While the lock does not specifically mention weather resistance, its steel construction suggests a certain level of durability against the elements.
