Provides the counterweight for the lifting door. You should always use two counterweights that correspond to the weight of the door. The length l of such a counterweight can be roughly calculated as follows:
l [mm] = m x 26 [mm/kg] - 11 [mm]
Mass m [kg]: Weight of the lifting door

Is screwed to the rear of the Lifting-Door Guide Profile. The counterweight runs inside this profile and a Conduit Profile 80x80 SE locks into position on top of the Support Profile to cover the counterweight.
