The 4-Post Shelving Assembly with Tiered Garment Rack provides a versatile, high-density storage solution designed for demanding environments where space efficiency, durability, and flexibility are critical, including public safety facilities requiring secure prisoner property storage. Constructed from durable materials for long-term stability, the system integrates seamlessly into a High-Density Mobile Shelving configuration, allowing garment racks to support organized hanging storage for property bags, uniforms, and accessories. Mounted on mobile carriages that glide smoothly along precision-aligned steel rails, the system significantly reduces fixed aisle space while maximizing both vertical and horizontal capacity—delivering up to three times more storage per square foot than traditional static shelving. Fully integrated as a Revit family, the system allows real-time adjustment of configurations and accurate representation of technical specifications, making it an ideal choice for custom, high-density storage planning across public safety, institutional, and commercial applications.
