Abstract: Described are embodiments of a portable crimping device for creating frame assemblies. The device includes in embodiments a rod that is movable from a first position to a second position. A head is connected to the rod, and a stud is connected to the head. When the rod is moved from the first position to the second position the stud engages a rail of a frame and deforms a portion of the rail, which secures a bracket in a channel of the rail. A second rail can then be secured to a second side of the bracket in a similar way to create a corner of a frame. The process can be repeated to generate an enclosed frame assembly for holding items such as photovoltaic panels.
