I use this bag to house my Dewalt D51822 clip Head Framing nailer . other have complain about how they nailer fit in this bag , but my Dewalt fit great with a little room to spare . the material be strong and do not seem like it will rip , tear , or fray easily . the zipper and other hardware ar extremely tough and will probably last a life time . the bottom of the bag be semi-rigid and offer extra protection when it be place on the ground .
