Security hardware for entrance doors

In the case of security hardware for entrance doors, a knob is often fitted to the exterior side of the door, which prevents the opening of an unlocked door. On the interior side an appropriate half-set for interior doors can be fitted.

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

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.

To be noted

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 right

Handle showing to the left

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.

Window handles

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

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.
