Alex o single non tilt

Thanks for reaching out! Your channel balance appears to be the Series 395 balance with a winged top guide and wingless bottom shoe attached. 

Unfortunately, I am uncertain what you mean by the "stay". If this is in reference to the length of the metal channel, you'll need the S395-28. Although, to be sure, I would suggest double checking the length metal channel, not including the top and bottom attachment.

Once you've confirmed the balance length, you'll be able to select it from our list of Series 395 balances but clicking the link. There is a chart that list the weight ranges each stamp option can carry to support the weight of the sash.
