Need to replace these parts

Thanks for writing in. This sash lock appears similar to our 90-323, but review the dimensions below and see if you think it will work for you. For the channel balance, I am afraid that stamp only tells us the strength of the balance, not its identity. We will need pictures of the fittings on either end of the metal channel. From there we'll do our best to assist you. See the video below for reference.
