The adjustable system for the lining of pre-frames or partitions for the adaptable installation of doors, with all widths of partitions and pre-frames consists of three parts: a central part or Column 2, with two lateral seatings 4 and 6 in which the male parts 5 and 7 of the seals or jambs 1 and 3 are set respectively. The male part 5 can be more or less accommodated in the seating 4, depending on the width of the pre-frame or partition, which enables the system to be adapted to any width of pre-frame and partition. <IMAGE>
