Which drive type for garage door openers is typically the least expensive?

The chain drive is generally recognized as the least expensive drive type for garage door openers. This is primarily due to the simplicity of its design and the materials used in its construction. Chain drives utilize a metal chain to lift and lower the garage door, which is effective and commonly used in residential applications. The durability of the chain, along with the cost-effective manufacturing processes associated with this type of opener, contribute to its lower price point compared to other types.

In contrast, belt drives, while quieter and smoother in operation, typically incorporate rubber or polymer belts, which can drive up the cost. Screw drives offer a more complex mechanism requiring threaded rods and can also be more expensive due to their unique design. Jackshaft drives involve a different mechanism that is attached to the wall beside the door and are often higher-priced due to their specialized installation and components. Thus, while each drive type has its own advantages, the chain drive stands out for its affordability, making it a popular choice for budget-conscious consumers.
