This gas strut provides controlled lifting and damped lowering of the cab window or hatch on the host agricultural machine. It is installed inside the cab and acts as a pneumatic spring, using compressed nitrogen to counterbalance the weight of the panel. When the strut loses gas pressure, the window or hatch will no longer stay open and may drop suddenly. The manufacturer machines the strut to match the original mounting geometry, so the end fittings align with the cab brackets without modification. On replacement, ensure the piston rod is extended fully before installation and that the retaining clips seat completely in their grooves.
