Most of the handles are universal ( can be install in left or right doors).

Groups of locks which requires the determination of left-right side:

  • Handles fo interior doors
  • Knob-lever and handrails
  • WC handles of some companys (f.ex. Gamet)


                       Left                        Right 

Attention! A lot of companys are using reverse designation of handles, so it’s the best to indicate door side according to the set out scheme.
