A door peephole is in the form of a small grille, placed on the outside, and a small shutter flap inside. This installation is particularly suitable for the entrance doors of pavilions or country houses. It allows to see the visitor and to question him without having recourse to an intercom. Inexpensive, it is both safe and decorative.

1. Place the peephole grille on the door to trace its location. It must be centered in relation to the amounts of the frame, and located at eye level of the users. It is better to place a peephole a little lower than too high. Make an identical tracing inside the house. Mark the location of the attachment points.
2. With the outline drawn on the door, proceed to a window cut, more precisely in a window. Drill two holes of large diameter in two opposite corners of the inner rectangle. Do this by preferably using a helical drill. The electric drill is not very useful here, a crankshaft is much more precise, equipped with such an accessory.
3. The cutting of the window is done with a window saw: the end of its tapered blade allows its introduction into the drilled holes. The "revolver" handle ensures a very efficient work. It is possible to use an electro-portable jigsaw, but the cutting is less precise than with a handsaw.
4. The outer grille, the inner shutter and its frame are joined by threaded rods, bolted from the inside. Drill the door from side to side at the location of the four attachment points. Use an electric drill and a wood drill with a diameter that matches the threaded rods. Make very precise holes so that the four rods are all parallel to each other.
5. Install the outer grille, threading the threaded rods into their seats.
These are integral with the grid: it is impossible to dismantle the installation from the outside.
6. Bolt this inner flap and its frame to the threaded rods of the grille.
Do it with a wrench or a wrench, not suitable. The shutter is equipped with a small lock can not be opened from the outside to look in the house.
