Merlin WeatherDrive MR550EVO




 Works every time thanks to Merlin Security+2.0

New Security+2.0 remote transmitters operate reliably under all environment conditions and from a greater distance than ever before. Thanks to the latest multi frequency technology the remote will operate even when there is interference from other wireless devices.


 Bright LED Lights

Driving into a dark garage and turning off your headlights can be a very dark experience! 9 LED lights provide energy efficient light that automatically switches on when the door is activated and switches off after 2½ minutes.






 Quiet and Powerful Motor

WeatherDrive's powerful and fast DC motor is quiet and built to last. It has the strength to open any size of door you have. You don’t have to question WeatherDrive, it is the perfect choice!


 Improved Remote Range

Tested in side by side comparisons* the Merlin WeatherDrive has up to 18% better range. Which means it is not only more reliable, you can also start opening your garage door sooner.
*Compared to major brands


 Adaptive Technology

Automatic power adjustment and electronic mapping of the door means WeatherDrive adapts to the change in door spring and hinge operation that naturally occurs with varying weather conditions and age. This technology means less maintenance and trouble free, reliable operation for years to come as the opener adapts to the door every time it is activated.





Security+2.0 technology inside the remote is designed to communicate on multiple frequencies with the latest Security+2.0 encrypted rolling code. This enhanced radio technology will select the strongest frequency every time, virtually eliminating interference from other devices. It provides the highest level of security available by using a unique code every time the button is pressed.


 Automatic Close

Forgot to close the door? Don't worry the timer to close option automatically closes the door. You can set a pre determined time up to 3 minutes. All you have to do to activate this feature is to install the optional safety beams (must be fitted) to ensure safe closing after you have left the garage.


 Safety Reversing System

Your safety and property protection is assured because the WeatherDrive has automatic safety reversing built in. If the garage door is obstructed while closing, it automatically stops and reverses, if obstructed while opening, it automatically stops.


 Ventilation Mode

Your door can also be stopped at any height to allow for ventilation by simply pressing the remote at any point in the travel to stop the door.
