PRO-Drive crank-opener series

Whether for slimline, pitched or arched windows, small side-hung applications or top-hung windows, Roto offers the right solution for all requirements. The PRO-Drive 2-bar crank-opener has been specially developed for effortless operation of large sashes.

This smooth running crank-opener copes with sash weights of over 45kg. A torque safety-catch and sealed housing system prevent the crank-opener from being damaged. The sealed housing virtually eliminates air and water penetration.

The variety of colours and compact design make this high-quality crank-opener attractive for builders and architects.
