A cartridge pleat is a drapery header type that uses rolls which create a template for loose waves to flow throughout the rest of the curtain. From an aerial view, the fabric simply looks like a zig zag with rounded edges. A cartridge pleat creates a layered and tailored aesthetic. The pleats can be enforced using pleater tape and pleater hooks which ensure that the pleat stays in place and lays properly. The pleater hooks are dual purpose, as they synch together the fabric to form and keep pleats, while also having a loop at the opposite end that allows it to be attached to a rod. Curtains with cartridge pleats can be hung using hardware such as rod and rings, an exposed track, a hidden track with cornice, or a curved track.
