In one embodiment, the front catch plate accepts the cartridge neck from an opening on the top side of the front catch plate. A plastic insert is attached to the front catch plate and provides a custom fit base for the specific form, shape and size of the cartridge neck used. There is a separate plastic insert for each different commercially available dual cartridge. In this embodiment, the front catch plate will generally be manufactured as one piece with the carriage.
