The image shows a set of two high-security vending machine tubular plug locks alongside their matching circular barrel keys.⚙️ Specifications & FunctionalityLock Design: These are standard 7-pin ACE-style tubular lock cylinders (also known as barrel plug locks). They feature a spring-loaded or deadbolt retention pin on the side. Mechanism: When inserted into a machine's spring-loaded T-handle or L-handle housing, turning the key causes the side pin to snap out, deadlocking the handle into place. Turning the key backwards retracts the side pin, allowing the lock cylinder to be pulled free so the handle can pop open. Universal Fit: This specific 1.5-inch style is a universal format used consistently across beverage, soda, snack, cold-food, and currency changer machines produced by major manufacturers like Dixie Narco, Crane National, Royal Vendors, Vendo, and Seaga. Brand New. Never Used. Each set contains 2 Locks with Keys #vendingmachinelocks #universalfit
