Replacement Casement Window Operator for 2005 Era Marvin Window

Thanks for your post! This operator is no longer made but the 39-171 Truth Hardware Dyad Operator should work as a suitable replacement. It does have a longer arm, so you may potentially need to adjust the bracket on the bottom of the window sash.

I've tagged a few of the other compatible hardware and accessories below.
