Manual Cascade-KOOI Reachforks® stay on the forklift truck permanently, saving time, space and money compared to traditional fork extensions (outer-sleeves). This mechanical option is a simple solution with a prompt payback, making it ideal for low usage applications. The manner of adjusting the outer sleeve is highly innovative. It simply involves moving a pin (which also serves as a grease nipple) sideways, causing the lock to be retracted. As soon as the lock is disengaged, the outer sleeve can be moved using the other hand until the lock engages again at the different length.
