A gate spring closer is a device used to automatically close a gate after it has been opened. It typically consists of a metal spring mechanism attached to the gate and the adjacent fence or post. When the gate is opened, the spring is stretched, and when the gate is released, the spring pulls the gate closed. Gate spring closers are commonly used in areas where it’s important to keep the gate closed for security or safety reasons. 12″ gate spring closer with heavy duty adjustable screws.
