About This Product

The Model 89-KL Piano Box provides a complete storage solution for tools, supplies, and other materials. Measuring 60 inches wide by 78 inches high when open (49 inches when closed), this job box offers 47.8 cubic feet of storage for all trades. Full-width interior shelves enable you to organize and protect tools, and the bi-fold cover opens upwards and folds completely out of the way for unrestricted access. 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 the-foot protection, featuring recessed, 7-gauge lock housing. Handles are also recessed to avoid damage during transit. Run power to the interior of the box with a grommeted, weatherproof Power Pass Electrical Pass-Thru. Gas spring guards prevent damage from shifting loads during transport. This workhorse features an improved ball stud bracket for added strength and greater durability. It also comes with a KNAACK Padlock that fit perfectly in the lock box.

                    you will spend time and money repairing
                    We own a fleet of over 300 Model 89 Piano boxes 250 old style with boxed-in channel skids and 50 of the new style four-way skid.. The switch from the older, boxed-in channel skids to Knaack’s newer four-way skid design, has caused us to spend time and money repairing or completely re-engineering the four-way skid. They bend and then the casters wont turn or collapse and they become a safety concern on job sites. We will have to find another brand if Knaack can't fix this issue.

At one of our job sites some meth heads did there best to break into our Knaack gang box. they had a whole weekend to try and get into it, but to no avail. Sorry fellas, better luck next time....

                        Upon arrival I discovered the box was beat up. I contacted HomeDepot who in turn instructed me to contact Knaack directly. As they apparently didn't want to deal with it.

                        All I can say is thanks!
                        The Knaack secure box definitely did what it is designed to do. I had roughly 15k in tools in this box. Box is ruined but the company and the employees tools were safe. Thanks again Knaack!

                          Knaack Quality
                          I have bought Many Knaack boxes in the last 14yrs . I can say they used to be the best , but their quality has sure went downhil !!!! I am very upset they don’t take the same pride they used to in their products. 3 new boxes delivered today, and struts not tightened, slim thin paint job, dents, welds are terrible.

                            Easy to break Into
                            Was excited to get this box to secure my tools. Good space easy to roll. But needs more welding spots on the door hinge. Box was broken into, looks like they used a crow bar and peeled the hinge and stole all of the tools. Haven’t found a replacement door so. I am down a site box now

                                Very disappointed with four way skid design.
                                We have been very disappointed with the new four way skid design. I have bought multiple knack boxes with casters bolted to the four way skids. On all of the boxes we have bought with the new four way skid design have failed structurally. This was caused by just pushing loaded box through job site by hand. See photo's P.S. I still have multiple older boxes with (boxed in skids) and have never had this problem.
