Sentry 300 070510 Electric Gate Lock Overview
The Sentry 300 070510 electric gate lock is a bolt-on, low-voltage locking accessory for compatible swing gate operator installations. It is designed to hold the gate in the closed position and release automatically when the gate operator receives an open command. This helps reduce gate movement caused by wind, gate flex, slope, or light pressure against the gate leaf.
This is not a universal latch for every gate. The lock, strike pin, gate stop, actuator timing, and control-board output all need to work together. A poorly aligned gate, sagging hinges, or excessive gate bind can prevent the lock from releasing cleanly and can damage the operator or lock mechanism.
Compatible With
Use this lock with select USAutomatic/Sentry swing gate operator systems where the control board and gate layout support the 070510 electric lock.
- Sentry 300 swing gate opener systems when wired for electric lock operation
- Sentry 300S single swing gate installations requiring a closed-position lock
- Sentry 300D dual swing gate installations when the lock is properly located and wired
- Select USAutomatic swing gate operator systems using compatible 12 VDC lock control
- Residential, farm, ranch, estate, and light commercial swing gates where the gate structure allows bolt-on lock mounting
- Not intended as a slide gate lock or as a substitute for correcting a dragging or misaligned swing gate

Technician Note
Before replacing the lock, check gate alignment, closed stop position, strike pin wear, wire condition, and whether the operator is sending release power before actuator movement. Lock binding is often caused by gate movement or hinge problems, not the lock alone.
Before Ordering Checklist
- Confirm the gate is a swing gate and the system supports an electric lock output.
- Verify the lock part number and compare the existing mounting style.
- Check that the gate closes consistently against the correct stop point.
- Inspect the strike pin, catch assembly, wiring, and control-board lock output.
- Do not use the lock to force a poorly balanced or dragging gate to stay closed.
Professional Advisory
Electric lock wiring and gate timing should be verified by a qualified gate technician if the gate moves before the lock releases, binds at the catch, or has unsafe closing force.
Product Questions
What does the 070510 electric gate lock do?
It secures a compatible swing gate in the closed position and releases when the operator receives a valid open command.
Can this lock fix a gate that sags or drags?
No. The gate must swing freely and close squarely. Hinge, post, or alignment problems should be corrected before installing or replacing the lock.
What voltage does the 070510 use?
The lock is a low-voltage DC accessory commonly specified for 10 VDC to 14 VDC operation on compatible systems.
Is the 070510 used on slide gates?
No. This product is intended for compatible swing gate lock applications, not slide gate locking.
Why is my electric lock clicking but not releasing?
Common causes include strike pin bind, gate pressure against the lock, low voltage, damaged wiring, weak battery, incorrect timing, or a mechanical alignment issue.
