1800 638 234New solution for light commercial and heavy residential roller doors
For those looking to automate large or heavy roller doors found in residential or light commercial applications, the recommended replacement product is the Grifco LR-Drive, a product sold under Chamberlain Group’s commercial door brand.
The Grifco LR-Drive has been specifically designed for large and wind-locked roller doors. The LR-Drive is:
- Faster: The LR-Drive opens a 2.4m high door in only 21 seconds. It is the fastest in its class!
- Stronger: The powerful motor and gearbox can lift roller doors up to 28m².
- Thinner: The incredibly thin operator requires only 45mm of side room clearance.
- Smarter: The Grifco LR-Drive’s smart myQ technology allows you to control the garage door via the myQ app from anywhere in the world.
The LR-Drive is also ideal for shopfront roller grilles thanks to commercial terminals that allow dedicated open and closing.
The Merlin OverDrive MRC950EVO garage door opener is no longer available for purchase. Customers who have installed a Merlin OverDrive MRC950EVO in the last two years will still be covered under the 2 Year Warranty.
