ABUS FG300A Lockable Window Handle with Alarm, White ABFG71902

Homeowners and facility managers who want to secure inward-opening windows and balcony doors without complex wiring will appreciate the ABUS FG300A.

Why choose it

The FG300A upgrades a standard window handle to an active security device. Its vibration sensor detects forced opening attempts and triggers a piercing alarm, while the lock cylinder withstands over one ton of pressure. The handle is surface-mounted and replaces existing hardware with standard 43 mm drilling distance, making installation straightforward.

Ideal use cases

• Ground-floor windows and easily accessible balcony doors
• Rental properties where wired alarm systems are impractical
• Retrofitting older windows with modern security
• Child safety: lockable handle prevents unauthorized opening

Good to know

The alarm unit is powered by two AAA batteries that last about two years, with a low-battery indicator to alert you before power runs out. The handle is finished in white (RAL 9010) to match common window frames. Two keys are supplied for the push cylinder lock.
