Bi-fold Gate Safety
Automatic gates are heavy. Safety is not optional.
Bi-fold-Specific Safety Considerations
Bi-fold gates have squeeze spots at every fold. Each fold needs a sensor. The panels also move up when folding. Watch for overhead hazards.
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: Bi-fold
Bi-fold Gate At a Glance
| Min width | 8 ft |
| Max width | 30 ft |
| Space needed | Little - folds to about 25% of opening |
| Best for | Flat driveways, Tight spaces |
| Opener type | Hydraulic or arm opener |
Bi-fold gates fold like an accordion. A 16-ft gate folds to about 4 ft when open.
Bi-fold Gate: What to Know
Best for: Tight spaces. No room for swing. No room for sliding track. A 16-ft gate folds to 4 ft. Perfect for small lots and courtyards.
⚠️ Watch out: Wind. When partly open, the panels act like a sail. In windy areas (30+ mph), wind can slam the gate. That can damage the hinges.
💡 Pro tip: Bi-fold opens and closes 40-60% faster than swing or sliding. On a busy street? You block traffic for less time. Big plus.

| Factor | Swing | Sliding | Cantilever | Bi-fold |
|---|---|---|---|---|
| Space needed | Full arc radius | Side track run | 1.5× width lateral | Minimal |
| Max width | 20 ft | 40 ft | 60 ft | 30 ft |
| Slope tolerance | Poor | Fair | Excellent | Poor |
| Typical speed | 12-18 sec | 8-14 sec | 8-14 sec | 6-10 sec |

💡 Bi-fold Gate (Wood)
Seal the top edge of every panel. Not just stain. Epoxy. When folded, the top catches rain like a shelf. Unsealed = rot in 3-4 years. From the inside.
