Bypass door Bottom track guide

Hi there Herman.

Thanks for reaching out to us. I believe this was used on Stanley brand heavy duty sliding doors. I'm afraid we don't sell the part shown here, however. The closest thing in our inventory appears to be the 23-081. This has a convex wheel that rolls in the bottom door track. It has mounting screws that are similar to yours as well. Take a look at the specifications for this part and see if you think they could work for you.
