Storagemaster Chest Boxes

Storagemaster Chests are the workhorses on any jobsite, ideal for every trade: mechanical, plumbing, HVAC, electrical, rough and finish carpentry. They’re caster–ready and include full-width shelves for organization of small to large tools and supplies.

Professional job sites require more than basic containment; they demand a mobile command center that secures high-value assets against theft and the elements. The StorageMaster chest provides this specialized level of protection, offering a reinforced piano-style build that serves as the ultimate workspace fortress. These units ensure your most critical tools remain organized and impenetrable behind a professional-grade steel barrier.

A Knaack StorageMaster chest is the benchmark for trade professionals who cannot afford the downtime of lost or damaged equipment. Built with the patented WATCHMAN IV Lock System, these chests provide a double-locked defense that is virtually impossible to pry open or drill. This level of security transforms a standard knaack gang box into a long-term investment that safeguards thousands of dollars in specialized inventory.

Ergonomic Command Centers 

The true value of a storagemaster chest lies in its interior intelligence. Unlike deep bins where tools get buried, the Knaack piano box architecture features full-width shelves and the innovative Junk Trunk™—a heavy-duty independent drawer for smaller, high-frequency items. Whether you utilize a Knaack 89 StorageMaster piano box for its massive 47.8 cubic feet of space or a ramp-equipped model for rolling heavy gear, you are buying an organized workflow. This Knaack StorageMaster series is the professional’s choice for a box that works as hard as the crew it protects.

FAQs

1. What is a Knaack StorageMaster chest and how is it different from other job site boxes?

The StorageMaster is an elite piano box that combines massive storage volume with advanced organization. It features an angled lid for full visibility and specialized drawers, making it a functional workstation rather than just a simple storagemaster bin.


2. What sizes and configurations are available for Knaack StorageMaster piano boxes?

Inventory ranges from the compact 35.3 cubic foot knaack storagemaster chest to the high-capacity 57.5 cubic foot models. You can choose configurations with ramps for easy loading or dual Junk Trunk™ drawers for maximum sorting.


3. How secure are Knaack StorageMaster chests and what lock system should I use?

Every knaack storagemaster unit utilizes the Watchman IV system, providing a deadbolt-style lock that resists prying. This keyed system is integrated directly into the box to shield the padlock from bolt cutters.


4. Can Knaack StorageMaster chests be customized with shelves, drawers, or casters?

Yes, most models come pre-equipped with full-width shelves and can be fitted with heavy-duty casters for mobility. This modularity ensures your StorageMaster serves as a tailored tool management solution.
