Product Details
The Knack Model 90 Storagemaster® piano box measures 72"W x 78"H and has a capacity of 57.5 cu ft, making it suitable for various trades. It is caster-ready and includes full-width shelves for organizing shovels, 4' levels, transits, and tools. The box features a bi-fold cover that folds completely out of the way, providing unrestricted access. Technical attributes include the use of an accessory door shelf model, a Watchman® IV lock system with recessed lock housing for enhanced theft protection, and additional reinforcement between the lock and the side housing. The design incorporates bigger, stronger hinges that resist pry-ins and a Power Pass® electrical pass-thru grommet for easy, weatherproof power cord access. The heavy-duty hinges enhance durability against pry-ins, while the powder-coat finish offers superior resistance to corrosion. The four-way skids allow access from any side for easier transport, and the closed height is 49" with an open height of 78". The caster-ready feature includes 14-gauge steel skids to accommodate optional casters, and recessed handles provide positive grip even when wearing gloves. Gas spring guards prevent damage from shifting loads, and an improved ball stud bracket offers added strength, reduces potential breakage, and enhances durability. As a versatile storage solution, the Storagemaster® is ideal for mechanical, plumbing, HVAC, electrical, rough, and finish carpentry trades.
