High Density File Shelving


High-Density Filing System: High-density filing systems are designed for professional office and clinic settings, with strong frames and shelves for supporting large quantities of file folders. Sliding file systems and expandable starter and add-on file systems are examples of high-density file systems.

High-Density Filing Tiers: High-density filing tiers refer to the shelves within a high-density filing system. The shelves are often reinforced or composed of strong materials to support large quantities of file folders. A 7-tier high-density file system will include filing units with seven shelves each.

Stationary High-Density File: Stationary high-density files are filing systems, often with shelves and shelf dividers, designed for positioning in one place. This is in contrast to the sliding file systems.

Sliding High-Density File: Sliding high-density files include multiple shelf units designed to support large quantities of file folders, and arranged with a track system for sliding the front shelf units to access the back shelf units.

Starter Unit: A starter unit describes the freestanding beginner unit of a high-density file system. The starter unit can be used alone, or combined with matching add-on units for customizing to suit different needs. Add-on units can usually be added at any time, allowing high-density file systems to expand with growing needs.

Rotary File: Rotary files typically refer to filing units with a central post-style frame that allows the shelves to rotate 360° for access from any side. The rotary file is often built within a storage unit, with front access only to enhance security, containing the sides and back of the file system within the storage unit but allowing full 360° rotation to access all contained files.

Expanding File System: An expanding file system typically includes a freestanding starter unit that can function alone or combine with non-freestanding add-on units for increased high-density filing as needed.

Tambour Door Cabinet: Tambour door cabinets are cabinets with a retractable door design, often with lock for security. The tambour door is somewhat flexible, allowing the door to slide open and simultaneously retract within the storage cabinet or compartment for space-saving accessibility.


Reinforced Steel Tracks: Reinforced steel tracks come with select high-density file systems, placed on the floor and adjusted with a series of leveling glides to stabilize and level the corresponding file units. The tracks allow the file units to be organized two units-deep, with the front units sliding to allow access to back units.

Heavy-Duty Aluminum Track: Heavy-duty aluminum tracks come with select high-density file systems, supporting an impressive 3500-pounds per track and allowing front filing units to slide laterally, easily providing access to back filing units for space-saving large quantity filing in business, school, or clinic office.

Fixed Shelf: Fixed shelf refers to filing shelves or tiers with only one allowable position within the filing unit. Most high-density file systems have fixed shelves, accommodating a set amount of file folders in a given size. Fixed shelves reinforce structural support and enhance durability of the overall file system.

Adjustable Shelf: Adjustable shelf refers to a shelf with multiple positions allowed within a file unit. The shelf will include support pegs or shelf pins that fit into pre-set spaces along the inner sides of the file unit, ensuring a balanced position at one of multiple heights. Most high-density file system shelves are fixed shelves.

Dividers: Dividers are included with many high-density file systems, allowing shelves to be divided into sections or allowing the dividers to support standing file folders on less-full shelves.

Leveling Glides: Leveling glides are incorporated in the base or sliding track designs, allowing the high-density file system to level on uneven floors for ideal positioning and use.

Backstop: A backstop is usually a bar or partial back panel that prevents file folders from sliding off the backsides of shelves within a high-density file system.

Full Back Panel: A full back panel on a high-density file system unit will completely enclose the backside of the filing unit, preventing file folders from falling off the backs of shelves when pushed into place.

Construction Materials

Environmentally Friendly Powder-Coat Paint Finish: Environmentally friendly powder-coat paint finish is a dry powder-coat paint applied to metal, usually steel, components of high-density file systems. The paint is cured for an eco-friendly finishing process that yields a durable, often scratch-resistant protective finish that lasts. The finish is usually smooth and non-glossy unless otherwise specified.

Pre-Assembled: High-density file systems that are listed as pre-assembled are delivered fully assembled and ready to position and use immediately upon arrival. With sliding file systems, the tracks or rails will require setup in advance but the high-density filing units and shelves are fully assembled when shipped.

Ready to Assemble: Ready to assemble refers to high-density filing systems that require assembly prior to use. These units will include necessary hardware but may require standard tools to assemble, such as screwdrivers.


Add-On Unit: Add-on units refer to the matching non-freestanding units designed to combine with the freestanding starter unit of a high-density file system. The add-on units allow virtually unlimited expansion to grow the filing system as needed.

ANSI/BIFMA: ANSI stands for the American National Standards Institute and BIFMA stands for the Business and Industrial Furniture Manufacturers Association. Both organizations are responsible for establishing and verifying design and safety standards of business-ready furniture and storage units. Many high-density file systems are tested and listed as meeting ANSI/BIFMA standards to simplify the shopping process.

Anti-Tip Mechanism: Anti-tip mechanisms are included with many filing units, including high-density file systems. The mechanism helps prevent the taller shelf units from tipping forward or back for safer use.

Green Features: Green features of high-density file systems usually refer to the use of environmentally friendly powder-coat paint finish on steel or other metal components. The use of eco-friendly finishes and/or partially or all recycled materials may also be green features depending on the design and manufacturer.

HIPAA: HIPAA stands for the Health Insurance Portability and Accountability Act of 1996 and refers to the standards set for organizing patient healthcare and insurance files, documents, records, and personal information in such a way as to ensure privacy and protection. High-density file systems listed as HIPAA compliant are verified to meet the standards set under HIPAA.

Legal-Sized Files: Legal-sized files are those that accommodate the legal-sized 8½” by 14” documents typically referred to as legal-sized documents. High-density file systems are designed usually with a fixed size, allowing shoppers to select letter-size or legal-size when purchasing, based on individual filing needs.

Letter-Sized Files: Letter-sized files are those folders designed to hold standard 8½” by 11” copy-paper document sizes. When not specified overtly, most file systems are designed to accommodate letter-sized filing by default.

Weight Capacity: Stated weight capacities for high-density file systems, shelves, or sliding file units tracks refer to the tested and established maximum safe weight a given unit or component can support when the weight is evenly distributed. Exceeding the weight capacity can result in damage to the high-density file system, floor tracks, or shelves and void the warranty on the entire product.
