Crush Prevention Systems: Protecting Your Family

December 28, 2025 6 min read

Garage doors are the largest moving objects in most homes, weighing between 150-400 pounds depending on size and material. Without proper safety systems, a closing door can cause serious injury or even death. Fortunately, modern garage doors include multiple crush prevention systems that have dramatically reduced accidents. Understanding these safety features helps you protect your family and ensure your door is properly equipped.

Federal Safety Requirements

, federal law has required all garage door openers sold in the United States to include specific safety features. These regulations were implemented after numerous tragic accidents involving children. All openers must now include:

• Auto-reverse mechanism that responds to obstruction
• Photo-eye sensors that detect objects in the door's path
• Manual release mechanism for emergency operation

Photo-Eye Sensors

Photo-eye sensors are mounted 4-6 inches above the floor on either side of the door opening. One sensor emits an invisible infrared beam; the other receives it. When anything breaks this beam while the door is closing, the door immediately reverses direction.

Common issues with photo-eyes include:

• Misalignment from accidental bumping
• Dirty lenses blocking the beam
• Sun interference at certain times of day
• Wiring damage from pests or moisture

Test your sensors monthly by placing an object in the door's path. The door should reverse immediately without touching the object.

Auto-Reverse Mechanism

The auto-reverse mechanism is a backup safety system that reverses the door if it contacts an obstruction. This is calibrated based on the resistance the opener encounters during normal operation.

Test this feature by placing a 2x4 flat on the ground where the door closes. When the door touches the board, it should reverse immediately. If it doesn't, the force settings need adjustment.a task for professionals, as improper settings can compromise safety.

Pinch-Resistant Panels

Traditional garage door sections can create pinch points where panels meet.gaps large enough to catch fingers. Modern pinch-resistant designs eliminate these gaps through:

• Flush-fit panel joints
• Contoured edges that prevent finger entry
• Internal hinges that stay protected during operation

If your door has traditional sections with exposed hinges, consider upgrading to pinch-resistant panels, especially if children regularly access the garage.

Bottom Bracket Safety

The bottom brackets on a garage door are under extreme spring tension. Tamper-resistant bottom brackets prevent unauthorized adjustment, reducing the risk of injury from spring release. Never attempt to adjust bottom brackets yourself.this is one of the most dangerous DIY mistakes homeowners make.

Ensuring Your Family's Safety

Beyond mechanical safety features, follow these practices:

• Keep wall-mounted controls out of children's reach
• Never let children play with door remotes
• Teach family members never to race under a closing door
• Schedule annual professional safety inspections
• Replace openers manufactured before 1993

When to Upgrade

If your opener predates 1993 or your door lacks modern safety features, upgrading is a worthwhile investment in your family's safety. Today's systems are more reliable, quieter, and include features like battery backup and smartphone connectivity. Contact Raeford Garage Doors for a free safety assessment of your current system.
