The Double Euro Cylinder

The STRONGA Double Euro Cylinder transforms existing Euro cylinder doors into intelligent, keyless access points without replacing the entire lock. Supporting fingerprint, PIN code, RFID fobs and Bluetooth control via the TTLock app, it offers flexible access for homes, apartments and commercial properties. Its IP66-rated construction withstands harsh weather conditions, while anti-drill, anti-bump and anti-pick protection provide enhanced security. The adjustable cylinder design suits a wide range of door thicknesses, and USB-C emergency power ensures access even when the batteries are depleted. Designed for reliability, convenience and everyday security, STRONGA delivers a premium smart locking solution built to last.
