Patio door rollers

Hello,

We'd be happy to look into this for you but your photos are only showing the inside part of the roller assembly. We'll need to see the outer housing as well to confirm if the 81-004 could work for you, which is most likely still installed inside the door. 

To remove the housing, remove the door from the track and carefully lay it down on a table. Remove both bottom frame screws and carefully remove the patio door bottom rail from the glass. You can use a block of wood and a hammer to remove the rail. Then look inside the rail for a screw and remove it to then remove the roller housing.
