Our front door is twenty-five years old. During the months when the weather allows, we enjoy the air that flows through the glass louvers. Periodically the cranks fail so without them the window remains closed until replacement cranks can be purchased. Over the years the cranks purchased always seem to be of the same quality . . . these jalousie operators are manufactured in Taiwan. Installation requires patience and sometimes it's necessary to modify the assemblage. Never the less, the end result is the crank operators work, perhaps not as efficiently as the originals but they do open and close the louvres as expected. The price of a new jalousie window door has never been a consideration as these cranks are suitable replacements for the originals. We keep additional new cranks on hand just in case one is needed. Also one never knows if the manufacture of these essential louver operators comes to an end. After all these years of enjoyment the door would not serve our fresh air needs anymore. Pleased to know companies continue to make them . . . only wish they were made int the USA.

Nice product - I bought it to replace a 30 years old rusted out original part, and it fit like a glove. solid and Functions well

Well built and good quality, but I wish the stud that came with it to connect the link from the operator to the internal link that moves the glass slats was longer. It was too short to allow the e-clip that snaps onto the stud to hold it all together. I had to get a Dremel tool with a grinder wheel and grind down the thickness of the operator link to get the e-ring to snap into the slot on the stud
