I'm pretty sure these are Jeld Wen screen sliding doors. I believe this is your 84-139 can you confirm. The housing is the white plastic (not shown) with the cheesy plastic adjustment screw that has its own hole in the metal frame. After searching thru all your wheel assemblies the 84-139 looks like mine with the double spring roller and white plastic housing with the adjustment screw set up unless I'm not finding another one. Thank you. Dan

Hello!
I agree that this looks like the wheel cartridge in our 84-139 screen roller assembly. As long as our dimensions match up to yours, you should be good to go.
