A Z-frame, as its name suggests, is designed in the shape of the letter Z. Used for inside mounting, part of the Z sits inside the window, while the other part creates a lip around the window. This ensures a clean frame around your window, avoiding any gaps around the window sill.
A Z-frame will protrude approx 9.5mm.
