Sliding screen door latch and handle

This has been a year long search for these parts and I have invested over $100 in unusable parts. Hole set is 3 1/2 inches. I do not know the door manufacturers name. Sliders were installed in 2007. I need 2 of the latch/handle assemblies. Your assistance is greatly appreciated.

please contact me at 

thank you!!

Thanks for your reply but that size is available at several local retailers and will not work for me.
thanks again

Hey Jefferson Indiana. I'm the the same position as you were. Looking for replacement latch for sliding screen door with 3 1/2 inch distance between holes.  Did you ever find a solution?
