Designed Around Your Collection

Museum Cabinets to Protect Every Item in Your Collection

Museum storage cabinets must do more than hold objects—they must safeguard them. Our museum cabinet line addresses this by combining airtight seals, reconfigurable interiors, and durable finishes with innovations that protect against light, moisture, pests, and handling damage. Engineered for spacing flexibility and long-term installations, these cabinets support growing, changing collections with ease.

Preservation Cabinets

Spacesaver’s 920 Series Preservation Cabinets are ideal for storing delicate items—from textiles to fossilized remains—and support long-term collection growth. Available in a variety of heights and depths, they feature adjustable trays, lift-off doors, and optional vents with replaceable filters. With UV‑protected tempered glass panels and non‑off‑gassing powder coats, they manage both protection and presentation.

Oversize Cabinets

The Model 395 Oversize Cabinet offers an impressive 181 cu ft of storage space for large artifacts like sculptures, armor, and architectural elements. Its bi‑fold and lift‑off door design, reinforced steel frame, and modular accessories make it a robust solution for oversized collections.

Archival Flat File Cabinets

Designed for maps, prints, blueprints, and other flat materials, our archival cabinets offer smooth stainless-steel rollers and full-extension drawers. With optional stacking bases, they can double as work surfaces while protecting sensitive media from bending or sun damage.

Botany Cabinets

Our full-height botany cabinets protect herbarium specimens with sealed compartments and fumigant-friendly airflow. They include pull-out reference shelves and adjustable interior spacing to support high-volume botanical collections with protection from pests, dust, and flattening.

Entomology Cabinets

Engineered for specimen drawer systems like Cornell, USNM, and Smithsonian, these cabinets offer gasketed seals, three-point latches, and lift-off doors for easy drawer access. Pull-out work shelves enhance usability, and heavy-gauge construction keeps specimens secure and preserved.
