The assembled window unit 22 is adapted to fit the openings I 8 of the door panels In and I2. Flanges 46 on rims 28 are arranged to fit against the inwardly extending flanges 20 of the door panels I0 and I2, thereby locating the window unit with respect to the openings IS.

Clamping means 48 may be provided on one of the panels, as shown in Fig. 6, so as to prevent any possible shifting of the window unit within the door. In the'clamping device shownin Fig'.
