Linear Actuator for A Frame

[Czars]

We just bought a T21QBHW and the third time we put the roof up that actuator died. Member Jacink posted that he had the same problem and the he replaced the actuator with a more substantial Duff Norton actuator rated at 1500 lbs. Does anyone know the particular Duff Norton actuator to use?

Do a forum search for roof actuator. There is info there about replacing your actuator with a Windy_Nation actuator from eBay.
