Using your DeWalt DWST17808 TSTAK I Tool Case is a breeze. First, you can customize the inside layout. Use the removable covered cups to store small items like screws and nails, and the removable dividers to separate drills and bits. You can stack multiple units on top of each other, just make sure to connect them with the slide latches for stability. When lifting the case, grab the bi - material handle on top for a comfortable grip. As for maintenance, keep it clean by wiping it down regularly with a dry cloth. Avoid exposing it to extreme moisture to prevent rust on the metal latches. If you're storing heavy tools, make sure not to exceed the 66 - lb weight capacity to keep the ball - bearing slides working well.
