Norwood Truth Casement and awning

Hello there. Your casement operator looks like either our 39-253LB & 39-253RB, or the 39-438B & 39-439B. The only difference between these two operator sets is the appendage at the end of the straight arm. The '-253' variety use the square 39-529, whereas the 39-438B and 39-439B use a rectangular piece that comes included. See the video below for more details. I am afraid neither of these operator types come in a stainless variety, though both are coated in an electrostatic powder that make them resistant to corrosion. For covers and handles that work with any of these mechanisms, see the 39-375 and 39-376, or the 39-451 and 39-452, depending on the style you prefer. 

For the awning operator, see our stainless steel 39-239C. This awning operator uses the 39-536 Pivot Slides and the 39-556 Track. For covers and handles that work with this assembly, see our 39-375 and 39-451. Let me know if you have further questions.
