Staples Adjustable File Cabinet Caddy - Fits Letter & Legal Files

Our review of the Staples Adjustable File Cabinet Caddy finds it a practical choice for offices and home workspaces that need to move full vertical file cabinets without strain. The bottom line: if you regularly reposition a 4-drawer vertical file cabinet or occasionally need to transport a letter or legal file cabinet within a building, this caddy delivers dependable mobility thanks to a sturdy frame and smooth wheels. Setup and adjustment are straightforward, and the unit is designed specifically to accommodate both letter and legal sized files while fitting standard four-drawer cabinets.

Key Features

• Adjustable length: The caddy adjusts from 16.8 in to 26.8 in so it can be customized to fit different cabinet bases for a secure fit.
• Designed for letter and legal files: The platform and support geometry accommodate both letter and legal sized filing cabinets without modifying the cabinet.
• Suitable for 4-drawer vertical cabinets: The dimensions and construction are intended to support standard four-drawer vertical file cabinets, giving confidence when moving full units.
• Smooth rollability: The wheels roll easily across typical office floors, making lateral moves and repositioning quick and low-effort.
• Sturdy build quality: Customers report a solid frame that resists wobble under load, improving safety during transport.

Who It's For

This caddy is well suited to office managers, facilities staff, and home office users who need a reliable way to move heavy file cabinets within a building. It works best when used with standard four-drawer vertical cabinets and when mobility, not long-distance transport, is the primary need.

People who need to move cabinets across uneven outdoor surfaces or who require a multi-function dolly for many furniture types should look elsewhere; this product is purpose-built for filing cabinets and excels in that role rather than as a general moving tool.

Our Verdict
