Product review (4 stars): May also work for other brands of washers / dryers
This wrench worked well for leveling my Haier HLC1700AXS with the open end. It's the perfect length and thickness to slide it in and level your washer or dryer legs quickly. Apparently the leveling hex nuts are commonly used across multiple brands (at least LG and Haier). Another review mentioned the open end is 17mm but I haven't yet measured to confirm, as it wasn't necessary. But it seems to fit the nuts snugly.
