Using the Knaack Model 51 tool tray is a breeze. Simply place it across the top of your JOBMASTER™ Chest opening. You can then put your small tools in the tray, and they'll be right at your fingertips when you need them. As for maintenance, since it has a tan powder - coat finish, you can just wipe it down with a dry cloth regularly to keep it looking good. Be careful not to drop heavy objects on it, as it's made of steel but still could get dented. Also, try not to expose it to excessive moisture to prevent rusting. With proper use and care, this tool tray will serve you well for a long time.
