Bottom snap in door roller

Thank you for reaching out to us. I'm afraid we don't sell a roller like what's shown here. I wonder if there is another piece of the housing that goes with this. Can you confirm? 

Thanks for confirming. The 23-042 and 23-074 come to mind, though the housing is longer than yours. I can't make any promises but you might be able to incorporate one of these rollers to your door. Take a look at the specifications and see what you think.

No problem; good luck with the repair!
