I'm looking for a direct replacement for the Truth 21328A and 40903A hinge sash for my crank out window. The interior white plastic piece has broken. The color is like a bronze/gold color.

Hello,

It sounds like you might be looking for new casement operators. We'd be happy to help but we would need to see photos of your assembly with the window open so that the entire mechanism is visible. Thank you!

You requested that I send photos to help determine exactly the replacement for my old 21328A and 40903R that was actually installed back in 2000. I have read online that a LOT of people have had issues with the white internal piece breaking, just like mine. Please see pictures below.
The window has two identical locking mechanisms. The lock is located on the right hand side of the window frame looking from inside the house to the outside. I figure I will probably also need the 40903R piece since the replacement locks I have seen are different and have a thicker black plastic piece on the inside.

Thanks for getting back to us. Your casement lock resembles the 38-144, which uses the 38-276 and 38-277 keepers. Unfortunately, the internal plastic piece is not available separately but take a look and compare the dimensions to your part. Thank you.
