Due to their spherical shape and hexagonal footprint, the handles of the 40 series meet the security requirements as for the door opening using a tool. The latch is particularly strong and has a long tapered section that can compress large seals. These handles can be applied to all simple-wing modular systems for AHU, with a door thickness of 20/25 and 40/45mm. Different door thicknesses can be produced on demand.
