We’ve Got Flexible File Storage All Locked Up

Stak-N-Lok keeps documents and other vital materials secure, organized and accessible while providing one of the most flexible filing solutions available.

Its modular shelving units can be stacked to provide full-height shelving or used singly on a desktop, providing as little or as much secure file storage as you need, wherever you need it. Expanding is as easy as adding individual units as your filing needs grow.

Stak-N-Lok provides HIPAA-compliant security in a range of sizes including legal and letter size file depths. An optional retractable posting shelf is available to provide extra work space, along with optional dividers.

Like all of our storage solutions, Stak-N-Lok is manufactured in the USA with top-grade steel and durable powder-coated finishes for years of reliable performance. It is available in an array of colors and finishes and can be customized to complement your décor.
