Direct answer: The words describe what happens when power is lost. A fail-safe gate can be released so it can open more freely in an emergency. A fail-secure setup stays locked until you use its manual release, such as a crank.
The exact release method depends on the model. Read the manual before you assume a gate can simply be pushed open.
Direct answer: A foot release is usually faster: step on the pedal, disengage the operator, then move the gate. A fail-secure crank gives more controlled access but takes more work.
Neither is automatically “better.” The right choice depends on how you want the gate to behave during a power outage.
Direct answer: An AC gate opener normally runs from household or commercial AC power. A DC opener runs its motor from DC power and often uses batteries as part of the system.
Solar gate systems normally charge batteries and run a DC control system. That is why a model built for DC/solar is a better starting point than trying to add a panel to a normal AC opener.
Direct answer: Both matter. A gate opener can be under the weight limit and still be too long, or under the length limit and still be too heavy.
Use both limits from the maker. Then check wind, gate condition, geometry, and how often the gate moves.
Direct answer: A solid gate catches wind like a big sail. That can put much more force on the opener than the gate’s normal weight suggests.
An open metal gate and a solid wood gate can have the same length and weight but behave very differently on a windy day.
Direct answer: Continuous duty means the motor is designed for repeated operation without the short run-time limits found on lighter-duty motors.
It does not mean the gate can ignore every other limit. Gate size, heat, safety devices, power, and the maker’s use class still matter.
Direct answer: Measure the moving gate section, not just the driveway opening. Get the gate length, a good weight estimate, and enough room around the posts for the opener hardware.
Also note whether the gate swings or slides, whether it is solid or open, whether it opens uphill or outward, and how far power is from the gate.
Direct answer: Eagle publishes 27 feet and 600 pounds as the maximum gate rating for the Eagle 1000 FR. A 27-foot gate is therefore at the stated length limit, not comfortably below it.
The gate still has to be within the weight limit and roll freely. A solid gate exposed to wind can also be a much harder application than an open metal gate of the same length.

Direct answer: Eagle rates the 1/2 HP Eagle 2000 FR for a gate up to 45 feet and 1,000 pounds. The 1 HP FR version is also rated to 45 feet but raises the weight capacity to 2,000 pounds.
A 45-foot gate is at the published length ceiling. Gate condition, rollers, track alignment, wind exposure, and actual weight deserve more scrutiny than they would on a much smaller gate.
Direct answer: Eagle publishes 18 feet and 600 pounds as the maximum rating for the Eagle 100. An 18-foot leaf is therefore right at the model’s stated length limit.
Confirm actual gate weight, hinge condition, opening geometry, wind load, and how freely the gate swings before treating the published maximum as a recommendation.
