I assume the new wood floor is thicker than the tile you took out. The thicker wood would have raised the rollers on the inside of the slide, but wouldn’t raise the outside of the slide the same proportionate amount. There is usually an adjustment on the ends of the arms to raise or lower the outside of the slide. Just don’t get it into the top of the slide opening.
Does the slide fit flush against the outside when closed or does the top stick out?
