I need to replace the handle on my roll screen door, photo's attached. It looks very similar to one you offer, minus the thumb latch. Numbers on the inner part of the handle are as follows; inner handle reads 771J OX EXT. Outer half of handle reads 771H XO EXT. Hope this is helpful.
Thanks,
Dave

Hey, Dave. Please see our 83-122 Pella screen door handle set. I think you'll find this matches up to your hardware quite well.
