The compact set of manual reducers we offer is specifically designed for driving foundation screws up to 76 mm wide and 1,000 mm long into the ground. For optimum performance, we recommend the use of a two-speed screwdriver with a torque of at least 64 Nm.

The GSR 1:78 gearbox in this set features an innovative design with more moving gear parts. This allows the power moment to be transformed in such a way as to considerably reduce the load on the screwdriver, making installation of the ground screw much easier. With our set of manual reducers, you can carry out your projects with efficiency and precision, while guaranteeing professional-quality results.
