I am looking for weep covers for a window which is smaller than the others, you had already given me the size for the larger ones and will order when I get this one, Thank You for all your help.

It looks like the company improvised by making a weep hole for your stationary window in the glazing bead. I think you may be able to use our 26-186 to cover the opening, you would need to widen it a little to lock in the pins but I'm really not sure if it will hold in for you, and if it does, you would need to make sure water can still excape.
