This Siren Padlock Alarm not only secures your precious chattels, but also shrieks in uncontrollable rage if someone tries to gain access without a key. Whether 110 decibels for 10 seconds will be enough to rouse the populace to your aid is another matter, but at least it tried. $24.95.
Here’s simple and effective security that lets you (and the neighborhood) know when anybody’s messing around your buildings or valuables. When the lock is disturbed, an alarm sounds at 110db for 10 a full seconds. Great for pickup truck toolboxes, outside sheds, and patio chests, etc.
