中文简体The working principle of garage door end caps is relatively simple. The end caps are designed to attach to the ends of the horizontal tracks that hold the rollers of a garage door in place. They are typically held in place with screws or other fasteners.
The main purpose of the end caps is to keep the rollers from coming out of the tracks, which could cause the door to come off its tracks and potentially cause damage or injury. The end caps also provide a finished look to the ends of the tracks.
The rollers of a garage door typically have a small metal stem that fits into the track. The end caps are designed with a small opening that allows the stem of the roller to fit through, but prevents it from coming out of the track.
Garage door end caps are usually made of durable materials such as plastic or metal to ensure that they can withstand the weight and movement of the garage door. They come in different sizes and shapes to fit different types of garage doors.
Overall, garage door end caps play an important role in keeping your garage door running smoothly and safely. It is important to make sure that they are in good condition and securely attached to the tracks to prevent any issues with the garage door's operation.
