Alarm Padlock

Thunderbolt Alarm Padlock with 110dB Siren
Ideal for the first layer of defense on Box Trucks and Cargo Trailers.

Keep your valuables safe with the Thunderbolt® Alarm Padlock, designed with an advanced motion sensor that activates a powerful 110dB alarm, effectively deterring thieves before they strike. Engineered for durability, this lock features a corrosion-resistant body and a thick, reinforced stainless steel shackle, ensuring maximum strength and security.

For added versatility, the Thunderbolt® Alarm Padlock offers two modes: engage the alarm for heightened protection or switch to silent mode by simply reversing the shackle. Its weatherproof design guarantees reliable performance in all conditions, while the dual high-collar body prevents access to bolt cutters for enhanced defense.

Included with the padlock are three high-security keys and two interchangeable hasps: the short hasp with a 1" opening and the tall hasp with a 1.25" opening, offering flexibility for various uses. The alarm automatically resets itself, and the lock comes with two sets of pre-installed batteries for immediate, hassle-free operation.

For an added layer of protection, a visible Thunderbolt® warning label is prominently displayed on the lock, signaling its built-in siren to potential intruders. Ideal for securing box truck roll-up doors, trailers, motorcycles, bikes, construction equipment, and more, the Thunderbolt® Alarm Padlock delivers unparalleled peace of mind and top-tier security.
