The garage door is the largest moving object in the typical home and because of its size and complexity garage door safety is imperative. The following garage door parts can be dangerous. Familiarize yourself with these door parts and know how to treat them safely. And remember, always consult your Raynor Authorized Dealer for garage door safety information about your model.
A garage door section joint is the area between door sections.
People have been injured by attempting to close a garage door by placing their fingers in an open section joint and pulling down on the door. As a garage door safety precaution, however, never attempt to place your fingers in the section joint.
The corner brackets are the two brackets that are attached to the lower left and lower right corners of the garage door. The cables that lift your garage door are typically attached to these brackets.
Since these garage door cables are under high tension, the brackets could fly dangerously when disconnected. Only an experienced technician should service these brackets.
Garage doors are typically balanced either by torsion springs or extension springs. Extension springs are generally mounted just above the horizontal track, perpendicular to the closed garage door. They provide lifting power by stretching.
If an extension spring breaks, broken spring parts can cause injury by flying around the garage. However, a safety cable, installed inside each extension spring, can contain the spring and prevent injury. If you have extension springs but do not have a safety cable, call your nearest Raynor Authorized Dealer for a safety inspection. Only an experienced technician should service garage door springs.
Garage doors are typically balanced either by torsion springs or extension springs. Torsion springs are usually mounted above a closed door, parallel and horizontal to the top section of the door. They provide lifting power for the door by winding and unwinding while the door is opened and closed.
The torsion spring is under high tension and requires special tools for adjustment. Because of the high tension, the torsion spring, and any part associated with the counterbalance system, should be adjusted only by a professional. These parts include: the springs, the cables, the corner brackets attached to the cables, the cable drums, and the center bearing bracket that holds the torsion spring shaft.
Photoelectric Eyes and Sensing Edges
Photoelectric eyes are sensors that are mounted about 5 to 6 inches off the floor on both sides of a garage door. These sensors operate with a garage door opener and send an invisible beam across the door opening. If that beam is broken while a motorized door is closing, the garage door opener will cause the door to reverse direction to the fully open position.
A sensing edge is attached to the bottom edge of a garage door. When this sensor contacts an obstruction during the closing of the door, the opener will cause the door to reverse direction to the fully open position.
Federal law requires that all residential garage door openers sold in the United States since 1993 must include additional protection against entrapment, such as photoelectric eyes or a sensing edge. The law also requires that, if these sensors become inoperative, the opener will not function. Your garage door opener can be dangerous if it does not have these safety devices. Your Raynor Authorized Dealer can explain the cost and benefits of these sensors.
Lift Handles and Pull Ropes
A lift handle is a handle attached to the door that allows you to manually open or close a door. A pull rope performs the same function and is usually attached to the bottom bracket in the lower corner of the door.
The lift handles and pull ropes are intended for use with a door that is opened and closed by hand. But when an opener is attached to the door, the pull rope should be removed. Otherwise, they can snag or hook on people or loose clothing while the door is being opened by the operator. If you have a power outage and need to manually close your motor-operated door, don’t close the door by placing your fingers between the door sections. If you have questions about the safety of your door system, call your nearest Raynor Authorized Dealer for a garage door safety inspection.
Garage Door Openers
A garage door opener is a separate product from a garage door. Openers are electric motorized devices that open and close garage doors.
Most garage door openers include an internal reversing mechanism that causes the door to reverse when it hits an obstruction. However, garage door openers with inadequate or poorly maintained reversing mechanisms have caused injury and even death to children who are caught underneath motor-operated garage doors.
The sensitivity of these internal reversing mechanisms can fall out of proper adjustment so that the door will not reverse when it hits an obstruction. You should check your reversing mechanism monthly by setting a block of wood or a full roll of paper towels on the floor in the path of a descending door. If the door does not reverse after contacting the obstruction, call a garage door technician to examine and repair your door system.

Garage Door Remote Controls
Garage door openers are usually operated by a wall-mounted push button, a hand-held remote control, or a keyless entry pad that requires you to enter a numerical code.
Small children have been seriously injured by playing with the remote controls of motor-operated garage doors. Running under a closing door can be a deadly game. Do not let children play with or use the push button or any remote controls for your door. Keep all such controls out of the reach of children.
