I do recognize this roller, but it is unfortunately discontinued and no longer made. We actually sold it many years ago but our stock ran out sometime in 2015. I suspect it became obsolete long before that, too.
The only product we sell that comes close is our 81-243, but I cannot guarantee that it will work. I've never tried it myself. However I think it's at least worth considering, so look over our dimensions to determine if you could adapt this to install on your door.
