Handles and locks for interior doors: BB, PZ, WC set or knob?
The door handle is the part of the door you touch every day. Design matters when choosing, but so do the quality of the material, the price and whether the handle sits comfortably in your hand. The type of lock is just as important.

Types of locks for interior doors
- BB – hole for a standard key. A standard interior key, suitable for rooms and bedrooms.
- PZ – hole for a cylinder (FAB lock). Suitable for a study, dressing room or a room that you really want to lock.
- WC set. A keyless lock with a turn knob, ideal for the bathroom and toilet.
- Knob / PZ handle. A fixed knob on one side and a handle on the other, used for example on doors to utility rooms.

A handle to match the style of the interior
Square handles in black or stainless steel suit modern interiors. A gold or brass handle suits classic panelled doors. If you want a clean look without visible hinges, add concealed hinges to the handle.
Hinges and hardware
The hinges are always on one side, which is why all doors are either right-hand or left-hand. With classic rebated doors the hinges are surface-mounted, while with flush doors they are recessed and concealed. The hinges only need occasional lubrication; more in the article Maintenance of interior doors.
