Using the Knaack Model 21 tool tray is a breeze. Simply place it across the top of the opening on your KNAACK JOBMASTER™ Chest. You can then start putting your small tools in the tray, like screwdrivers, nails, and nuts. This way, you won't have to dig through the chest to find what you need. When it comes to maintenance, it's important to keep the tray clean. You can use a dry cloth to wipe off any dust or debris. If there are any stubborn stains, you can use a mild soap and water solution. Just make sure to dry it thoroughly afterward to prevent rust. Also, avoid overloading the tray. It's designed to hold a reasonable amount of tools, but putting too many heavy items in it could damage the tray or the chest. With proper use and care, your Knaack Model 21 tool tray will serve you well for a long time.
