The Frigidaire 134700400 38-Inch Stacking Kit helps securely stack compatible laundry appliances to maximize floor space. This installation kit is designed to safely position a compatible dryer on top of a matching washer, creating a stable vertical laundry setup. It works by using mounting brackets and fastening hardware to secure the appliances together, helping reduce movement during operation. Replacing missing or damaged stacking hardware, or installing this kit during setup, can help improve stability, optimize laundry room organization, and make better use of limited space.
