Manual Operators

Manual Operation is cost effective and best suited for applications with smaller doors, in buildings that don't have power, or in areas that will cycle infrequently.

ControlGard™ Chain Hoist

The ControlGard™ Chain Hoist features an integral braking system, so it only moves when the user is actively pulling the chain. This new operator boasts many benefits above and beyond standard chain hoists.

Push Up

Push up operation allows users to open our doors, grilles and shutters by hand without any additional devices. Choose this option when you have a smaller opening in a tight space that won’t fit a motor, will only be cycled a few times a day, and is not wired for power. This is the least expensive option for opening your door, and you often see this used in concession stands and retail spaces.

Chain

Chain operation allows users to open larger doors, grilles and shutters by hand with the assistance of a chain mechanism. As above, chain operation is good for tight spaces that won’t fit a motor, will only be cycled a few times a day, and aren’t wired for power. In addition to being very cost effective, chain operation opens the door in a less jerky and more consistent manner, ultimately improving door longevity.

Crank

Crank operation is primarily used in counter shutter applications where there is a wide counter space between the shutter and the user. You often see crank operation in lunchrooms or pharmacy counters. In that case, a rigid crank operation is ideal, since it can reach across the gap and open the shutter. Again, power is not required for this operation method, and it is best suited to infrequent daily cycles.
