The Model 79 STORAGEMASTER® Piano Box provides a complete storage solution for tools, supplies, and other materials on the jobsite. Measuring 48in wide and 49in high, this job box offers 38.2 cu ft of storage that fits perfectly in the back of a full-size pickup truck. Full-width interior shelves let you organize and protect tools, and the bi-fold cover opens upwards and folds completely out of the way for unrestricted access to the interior. A tan, powder-coat finish provides durable protection against corrosion, while a heavy-duty piano hinge protects against pry-ins and theft. A Watchman® IV Lock System aids further in this protection, featuring a recessed 7-gauge lock housing. Handles are also recessed to avoid damage during transit. Run power to the interior of the gang box with a grommeted, weatherproof Power Pass® Electrical Pass-Thru. Spring guards prevent damage from shifting loads during transport. You can access this jobsite storage box from any side, thanks to 7-gauge, 4-way skids.
