The Frigidaire 134639100 Leveling Leg provides adjustable support to keep a compatible washer stable and properly balanced. This replacement leg mounts to the bottom of the washing machine and can be adjusted to compensate for uneven flooring. Turning the leg changes its height, allowing the washer cabinet to sit level during washing and spinning cycles. Proper leveling can reduce rocking, shifting, and excessive vibration caused by an uneven washer position. A damaged, worn, or missing leg may affect stability and increase movement during laundry cycles.
