How to Determine Hydraulic Gate Closer Specifications
When selecting or replacing a hydraulic gate closer, the key measurement to consider is the Extended Length — the total length of the closer when fully extended, measured from the center of one end fitting to the center of the other. Ensuring this dimension matches your gate’s requirements helps achieve proper alignment, smooth operation, and reliable closing performance.
