The Alera ALESW504818SR is a heavy-duty wire shelving unit measuring 48 inches wide by 18 inches deep, designed for versatile storage in home, office, garage, or commercial environments. The "SR" designation indicates silver-finish chrome-plated posts, giving the unit a clean, professional appearance that resists corrosion and is easy to clean.

Each shelf features an open wire grid design that promotes airflow, reduces dust accumulation, and allows visibility of stored items at a glance. The shelves are adjustable in 1-inch increments along the posts, making it easy to customize the configuration for items of varying heights. The unit is compatible with other Alera wire shelving components, allowing for expansion or reconfiguration over time.

The shelving system is designed to support substantial weight loads per shelf, making it suitable for storing heavy tools, supplies, or pantry goods. Assembly requires no tools — shelves snap securely onto the posts using a lever-lock mechanism. The silver finish coordinates well with standard wire shelving accessories including shelf liners, label holders, and casters.
