Patio screen door latch

Is this for a screen door? We may not have this part by itself, but we do sell complete screen door handle sets. Look at our 83-002 as an example and let me know what you think.

Our 83-002 is an example of a screen door handle set that might be a replacement, but I can't really judge that just based on the inside latch mechanism. I recommend carefully looking over the pictures, dimensions, and information we show for the 83-002 to your own hardware to see how they compare.
