The magnetic weight compensation for the retracted state is pre-mounted either on the right or left side. It can be selected in the following steps to match the additional mass attached to the carriage: 600 g, 1200 g, 1800 g or 2500 g. The mass of the carriage is already taken into account - only the additional weight attached needs to be considered.

The weight compensation with spring force can be ordered either for the retracted or extended state and thus for your installation situation. It can be selected in the following steps to match the additional mass attached to the slide: 500 g, 1000 g, 1500 g or 2000 g. The mass of the carriage itself is already taken into account - only the mounted additional weight needs to be taken into account.
