Product Details
The Knaack Model 89 Storagemaster® piano box measures 60"W x 78"H and has a capacity of 47.8 cu ft. It is designed for mechanical trades and includes full-width shelves for the organization of tools and supplies. This model features a bi-fold cover that folds completely out of the way, providing unrestricted access. It is equipped with a Watchman® IV lock system with recessed lock housing for enhanced theft protection, and additional reinforcement between the lock and the side housing. The Power Pass® electrical pass-through grommet allows for easy and weatherproof power cord access, while heavy-duty hinges are extra durable and resist prying. The powder-coat finish ensures superior durability and corrosion resistance. The piano box includes four-way skids for access from any side, closed height of 49", open height of 78", and is caster-ready with 14-gauge steel skids to accommodate optional casters. Recessed handles enable positive gripping, even with gloves on, and gas spring guards prevent damage from shifting loads. An improved ball stud bracket provides added strength, reduces the potential for breakage, and enhances durability. This versatile storage solution is ideal for mechanical, plumbing, HVAC, electrical, rough, and finish carpentry trades.
