Casement vent window is 19"x13". Rivet for scissor crank broke. No markings on unit to identify brand, model, or part #. I need your help identifying what the replacement part would be for the entire crank unit.

Hey there. This is actually an awning window (it opens vertically, whereas the casement window opens horizontally). See the 39-239B or stainless steel 39-239C. See if this matches what you have. For a cover and handle, see the 39-451 or 39-375, depending on the style preferred. For the pivot sides, see the 39-536.

Bob,
Thanks for your help on this. You got me to the right products that I needed. While the stainless version is a nice option, the problem I'm having is with the corrosion build up on the mounting plate which freezes all the screws. I stripped one trying to take it out so I ended up drilling out the screw.
