BLK Classic 520 - Folding System
A completely new system which has the same design with all BLK's systems and can provide ergonomy. It is ideal for big openings in hotels, houses and entertainment places.


The sliding of the guidance mechanism is made with 4 rollers in a special designed internal driver in order that the system works perfect and noiseless. BLK Classic 520 uses two weather gaskets which offer the maximum seal. The assembling is made easy and quickly which give to the constructors suppleness. One advantage that BLK Classic 520 has is the construction of odd or even opening leafs, left or right opening, inwards or outwards which accomplish all the architectural demands.


With the use of a single cornice profile which covers any mistakes in the opening’s construction and with the use of two special adjustable regulators the construction can be leveled perfectly. BLK Classic 520 can embrace glazing up to 30 mm.
