Marantec Comfort KRA4224E Double Swing Gate Operator Kit
The Marantec Comfort KRA4224E is a powerful and reliable automation kit for double-leaf swing gates. Designed for gate leaves measuring up to 4 metres wide, 2 metres high and 600 kg, this premium 24 V system combines robust construction, precise movement and extensive programming options.
Each operator is equipped with an integrated encoder, allowing the control unit to monitor the gate position and movement with a high level of precision. Current-sensitive obstacle detection automatically stops and reverses the gate if an obstruction is detected, providing additional operational safety.
The operators feature a strong powder-coated die-cast aluminium housing, UV-resistant covers and protected internal mechanical components. The concealed drive mechanism and quiet operation make the KRA4224E suitable for demanding residential and light commercial gate installations.
Suitable for Double Swing Gates
- Maximum gate leaf width: 4,000 mm
- Maximum gate leaf weight: 600 kg
- Maximum gate leaf height: 2,000 mm
- Maximum opening angle: 120°
- For level swing gates without an incline
The actual permissible gate size and weight may depend on the gate design, hinge geometry, wind exposure and installation conditions.
