This is a cover for the battery well in Dewalt brand 20 Volt cordless tools to protect the contactors of the tool. The model also has two holes for mounting to hold the tool upside down, designed for gauge 8 flathead screws.
Surprisingly, the model was able hold a cordless jigsaw. I see no problem why the model should not be able to hold any of Dewalt 20 Volt tools, but do so at your own risk.
