81-013 discontinued replacement

We do still carry the 81-014, which is the inside housing portion only, as well as the 81-266 wheel and axle kit. Either one of these products may work but this is only assuming the rest of your housing is still in good working order. 

If you need to replace the complete roller housing in your door, you would need to retro fit something like our 81-002 into the bottom door rail. To install the 81-001 you will need to drill and counter sink a hole in the bottom rail under the glass door lit using the 33-103 mounting screw.
