Allomatic GCR-102 Gearbox Crank Release

Manual Override Crank for Compatible All-O-Matic Slide Operators

The Allomatic GCR-102 Gearbox Crank Release is a replacement manual override crank used on compatible All-O-Matic slide gate operators with a crank-style gearbox release system. This part allows the operator’s gearbox release mechanism to be engaged during service, troubleshooting, or power-loss situations where manual gate movement is required.

In perimeter access systems, a working manual release is important because the gate may need to be opened or moved when power is unavailable, the operator is disabled, or a technician needs to service the gate safely. The GCR-102 helps restore the crank-release function when the original crank is missing, damaged, bent, or no longer usable.

All-O-Matic lists the GCR-102 as the Gearbox Crank Release in the SL-100AC slide gate operator parts breakdown. It should be used only on All-O-Matic operators that are designed for this specific crank-release component and gearbox release configuration.
