Strong, durable, and clear for easy visibility of stored items. - EXTENDABLE DESIGN AND INSTALLATION: Rails extend from 11.2" to 18" to adapt to different shelf lengths. Smooth glide tracks ensure the drawer opens and closes easily. No tools required; installs in seconds. - USE SCENARIOS: - Organize dairy, yogurts, sauces, and small jars on a mid to upper fridge shelf for quick access. - Create 4-grid sections to separate snacks, condiments, or small produce for neat, at-a-glance storage. - Use with 2-grid or without grids on shelves with taller bottles to maximize space and accessibility.
