The MEILLER MOD Concept for landing doors is designed such that the frame including sill can remain in principle. The old transom will be stripped of all mechanisms and electrical parts.
The position of the new mechanical unit will be adapted on site in terms of height and depth and joined to the existing door panels by means of adapter plates. A new closing weight connection is provided as well as the adaptation to the existing emergency unlocking system.
If required, the door panels can also be replaced. New door panels can be optionally manufactured individually for the respective situation, just as with the MOD Concept for car doors.
The sill should be retained in any case. A new MEILLER car door will fit this purpose: either just a transom from the MOD Concept or a complete standard door. In each case, with MEILLER standard TM2-V skate to operate the hook locks of the new mechanism. The new MEILLER MOD Concept - the flexible solution for simple and efficient modernisation of landing doors and car doors.
