Looking for some serious security for your cabinets? These QWORK electronic locks are built tough with carbon steel and steel plate construction that'll keep your stuff protected. They work on a simple but smart principle - they stay locked when not energized and open right up when you apply power (DC 12V, 2A).

You get four locks in the pack, making it super cost-effective to secure multiple cabinets. They're super versatile too - perfect for storage cabinets, mailboxes, logistics cabinets, filing cabinets, vending machines, shoe cabinets, and pretty much any other application where you need reliable access control. Installation is straightforward, and the consistent performance means no more worrying about mechanical locks wearing out or keys getting lost.

Whether you're securing important documents, valuable equipment, or just want to keep certain areas restricted, these electronic locks deliver professional-grade security without the crazy price tag. They're one of those products that just work exactly as promised, day after day.
