Swing Gate Safety
Automatic gates are heavy. Safety is not optional.
Swing-Specific Safety Considerations
Swing gates have spots where someone could get caught. Where the gate meets the post. Where it meets the center. Sensors must cover the full swing path. Not just when closed.
Spots That Need Sensors
Every automatic gate has spots where someone could get caught. You need sensors to cover them.
| Spot | What to cover | Device |
|---|---|---|
| Gate edge | The front of the gate | Pressure-sensitive edge |
| Gate path | Full swing or slide path | Beam sensor (photo eye) |
| Closing point | Where gate meets post | Contact edge or second beam |
| Above gate | For tall gates | Overhead sensor |
When Power Fails or Emergencies Happen
- Manual release: A key to open the gate when power is out
- Battery backup: Gate works 24+ hours without power (recommended)
- Fire dept access: Key box or code so they can get in
- Walk-through gate: A small gate so people do not have to use the motor gate

Specs That Matter: Swing
Swing Gate At a Glance
| Min width | 8 ft (single panel) |
| Max width | 20 ft (two panels) |
| Space needed | Clear space for gate to swing - usually 10-12 ft |
| Best for | Flat driveways, Gentle slopes |
| Opener type | Arm opener or underground opener |
Swing gates are the oldest type. Simple. Reliable. Still the most popular.
Swing Gate: What to Know
Best for: Flat or gentle slope. Under 16 ft wide. Clear space on one or both sides. Two panels with underground opener = cleanest look. No visible motor.
⚠️ Watch out: Not leaving enough room. A 12-ft gate needs 12 ft of empty space to swing. No plants. No cars. No mailbox. On a slope, the gate can hit the ground on the high side.
💡 Pro tip: Swing inward if you can. Keeps the gate off the street. Hides the opener. Looks cleaner. Exception: steep uphill driveways where inward swing drags on the ground.

💡 Swing Gate (Wrought Iron)
Hinges should be bolted on, not welded in place. Welding on site can warp the hinges. A warped hinge means a sagging gate. For months.
