2. Do you have a “right-hand” or “left-hand” door (according to DIN, German Industrial Standard)?

   1. In cases of entrance doors to houses and flats, a knob is often fitted to the exterior side of the door. This prevents normal opening of the unlocked door.

      In the case of certain curved handle designs for the interior door side you need to ensure whether you need left-hand or right-hand specification.

      Example of a handle design where you need to be sure whether you need a right-hand or left-hand specification:

      
      Handle showing to the right

      
      Handle showing to the left

       

      In order to ascertain which one you want, stand in front of the interior side of your entrance door and check whether the hinges are to the left or the right on the door. In the case of a DIN left-hand door you need a handle pointing to the left and in the case of a DIN right-hand door, a handle pointing to the right.

      
      DIN right

      
      DIN left

3. Which measurements are necessary when buying your Handle of excellence?

   1. 1) Spindle size:

       

      Entrance and corridor door sets: A = 8 mm or 10 mm   Interior doors / WC doors: A = 8 mm   Turn buttons for Privacy / WC doors: B = 8 mm

       

      2) Distance between centre of lock follower and centre of keyhole:

      Entrance and corridor doors: C = 72 mm or 92 mm Interior doors: C = 72 mm   WC doors: C = 78 mm   3) Door thickness:   The door thickness affects the length of the spindle and screws required, so it’s important the exact door thickness is measured. The packaging shows the suitable door thickness of the handle set.

      In order to be able to choose the handles which are right for your doors, it’s important to compare the information from the check-list with the details on the packaging.

      Appropriate mounting items as well as detailed assembly instructions can be found with every HOPPE product.

Window handles

1. Are you able to replace your window handles easily?

   1. It’s easy to replace your present window handles with new ones, for example lockable window handles like Secu100^® + Secustik^® or Secustik^®.
      Turn the old handle to the opening position (horizontal). Then lift the cover cap slightly and rotate it by 90 °. Loosen the screw and remove the old handle. Now you can fit the new handle.
