Measure the width, depth, and height of the cabinet space, including any obstructions like pipes or a garbage disposal. Most organizers list a range of adjustable heights, so ensure the minimum and maximum settings fit your cabinet. Double‑check that the width of the sliding drawer can extend fully without hitting the side walls.

Look for the stated weight limit; most steel‑based models support 40‑50 lb per drawer, while plastic units may handle less. Heavy‑duty suction cups or 3M adhesive pads add stability for heavier loads. Consider the material thickness and reinforcement, such as a 1‑inch frame, for long‑term durability.

Ball‑bearing tracks provide smoother, quieter operation and can handle higher loads without wobbling. They also reduce wear over time compared to basic plastic rails. If you plan to pull the drawer frequently or store heavy items, the upgrade is usually justified.

A two‑tier system lets you separate tall bottles on the lower level while keeping smaller items on the upper drawer for quick access. It maximizes vertical space and often includes adjustable heights to fit irregular pipe layouts. Single‑tier shelves are simpler but may leave unused space above or below the drawer.

Anti‑slip components keep the organizer stable when you pull the drawer out, especially on smooth cabinet interiors. Suction cups are useful for metal or glass cabinets, while silicone pads work well on painted wood. Without them, the unit can shift, causing spills or damage to stored items.

Some models, such as the Delamu unit, are designed to be stackable up to three tiers, allowing you to customize the height based on your needs. Stacking works best when each unit has its own sliding mechanism and the combined height stays within the cabinet clearance. Ensure the stacked configuration does not interfere with plumbing or the cabinet door.

Stainless steel or carbon steel with a rust‑proof coating is ideal because it resists moisture and corrosion. Acrylic or high‑hardness ABS plastic can be clear and lightweight but may warp over time if exposed to water. A rust‑resistant finish combined with a water‑draining grid design offers the best longevity.

Adjustable height lets you fit around pipes and accommodate taller bottles, providing a more flexible storage solution. Models with multiple height increments (e.g., five settings) can be fine‑tuned for different cabinet sizes, reducing wasted space. The added versatility often justifies the higher price, especially in smaller kitchens.
