Crank openers Window shutters are a decisive and popular element in facade design and at the same time have an important function. They provide shade, darken rooms, defy wind and rain and protect against unwelcome guests. It is very practical if such all-rounders can be operated easily from the inside of the house, without having to open the window to do so: as with the optimised performance of MACO crank openers. MACO RUSTICO SHUTTER FITTINGS Crank opener: air and water-tight Within the framework of the increasing importance of thermal insulation and air impermeability in the construction industry, the term “leakage points” is cropping up more and more in the structural engineering arena (Catchphrase: “Blower door test”). The new generation of crank openers are proven to give a high-quality seal. As always, a rotary arm as well as hinges can be used for the transmission of power to the shutter sash. The internal hole diameter in the frame is 12 mm on both timber and PVC (on the inside). Insert the crank operator into the device on the inside to open and close the shutter!
