Lifetime Warranty Belt
Similar to a camshaft belt, this garage door opener model utilizes steel mesh inside a quiet and durable belt. This prevents you from getting the steel-on-steel grinding while maintaining the durability and longevity of a chain.

Lifetime Warranty 1 ¼ HP DC Motor
This is what separates our belt drive from the rest. Permanent lubrication through steel-enclosed gears, with self-adjusting force and limits. You can see AND hear the difference. All other openers use exposed plastic gear that wears out every 4 to 8 years. This motor ensures a longer life and smoother operation than any garage door opener.
