Casement Window Replacement Hardware in White

Thanks for reaching out to us. I believe you have an older Imperial Casement window which was made by BiltBest back in the 1960's. These original parts are no longer available. We can't promise our parts will work and adaptation will be required. With that said, take a look at the 38-075 casement lock which uses the 38-089 keeper. As for the operator, we have the 39-013/39-014 and 39-027E/39-028E which are compatible with the 39-533 track. 

You will need to review the specifications to see if you could adapt and retrofit this new style of hardware to repair your window. You might even need to make up new wood trim and operator sill covers for the new hardware. If you aren't comfortable doing so, contacting a local professional would be your best option.
