Replacement Crank Needed

Question

I need to replace a surface mount dual arm operator.  There were a few numbers on the crank I have - 410H, 410R, 41011.  Looks like the crank was manufactured in 2000

Hi there!

Take a look at our 39-253LB and 39-253RB operators, which use the 39-529 track slider. Compare our dimensions to yours and see how they match up.
