Guillotine-style Black (outside) / White (inside)

DOOR WITH FRAME DIMENSION: W: 33 1/2" or 35 1/2" x H: 82 1/2" x T: 7 1/4" with 2 standard handle holes.

This door features a built-in guillotine-style window that slides vertically within the frame, offering a practical and space-efficient way to open and close the window without swinging it outward or inward. Ideal for controlled ventilation, communication, or secure pass-throughs, the manually operated window uses a counterbalanced or guided track system for smooth, reliable movement. 

*Please note that the configuration options are described from an external point of view.
