FSF - Fail Safe Operator
Fail-Safe is the easiest and most convenient way to operate your gate during a power outage. Fail-Safe means when the power fails at the site, your gate automatically returns to manual mode.
Only Fail-Safe Gate Operators meet the most stringent standards of safety and convenience.
And Fail-Safe is the most reliable. There are no foot pedals, switches or electro-mechanical devices. These mechanisms are prone to bind, corrode and jam over time leaving your inoperable during a power outage.

FSC - Fail Secure Operator
Eagle Fail-Secure Gate Operators provides security during a power failure needed at many commercial and some residential sites. Fail-Secure allows you to open your gate when you want; manually, and only from the inside of the property.
Eagle Fail-Secure Gate Operators come with a small crank handle. Simply insert the handle in the side of the operator and turn to open you gate.

DM - Dual Motor
Eagle DM means Dual Motor. Dual Motor Eagle Gate Operators are designed for the most high traffic applications. This unique design utilizes two separate motors; one to open the gate and the other to close the gate.
While one motor moves the gate, the other motor rests and cools extending the life of your investment.
