Dampers from the „Light“-series can not be adjusted for load, therefore, they are priced lower than our other ranges.
The spring load rating of the „LT60N“ („or LT80N“) is determined such that a door with a maximum door weight of 25kg (50kg for LT80N) can be cycled up to 40 000 times, with the damper still functioning in line with specification thereafter.
On request, springs with a higher closing capacity (force rating) can be supplied from the outset.
