The Alera ALESW590004 casters are designed to add mobility to Alera wire shelving units, transforming stationary shelving into easily movable storage systems. This set includes four swivel casters that attach directly to the bottom posts of compatible Alera wire shelving frames, allowing the entire unit to be rolled from place to place with ease.

The casters feature a sturdy construction suitable for warehouse, garage, commercial, and home storage environments. Each caster swivels 360 degrees to provide full maneuverability in tight spaces. Designed to work with standard Alera wire shelving pole diameters, installation requires no tools — the casters simply press onto the base of each shelving post.

This set of four casters is compatible with Alera wire shelving units sold separately. Adding casters is ideal for pantries, utility rooms, garages, and commercial storage areas where shelf positions need to be frequently adjusted.
