At the DeWalt media event this past June, we got a sneak peak at the DS450, which will be available the end of this year. Built off of the ToughSystem platform, this hard-shelled box features a retractable handle, heavy-duty wheels for rolling up and down stairs, and a removable tray. It’s expected to sell for $70 to $80. In this video, contributing editor David Frane gives an overview of its functionality and features.
