This latch is very versatile for cooling units. Our multi-purpose latching system comes with a wide range of socket variants for different cold room door stops. The enormous versatility is made possible by a flexible modular system in which the handles are not only lockable, but also ready for master key systems. In addition, a Kaba version can also be requested. This system can be used for both left- and right-hand doors by simply rotating the flanges and inner socket to the appropriate position. The modern plastic latching system not only masters the highest demands, but is also quick and easy to install. The integrated tolerance compensation keeps both handles close together. The multi-functional latching system is suitable for door thicknesses from 80 mm to 200 mm. Even when the outside handle is locked, the inside handle still opens the door without overriding the locked state. 7503 Zeichnung
