I'm guessing this is your part #81-004?

Question

My part pictured is from a door of unknown brand. Says Production Enterprises on it. I think it's your #81-004, seems to match the measurements.

Thanks for writing in. Your roller does actually look similar to our 81-004 which was used on "Keller" patio glass doors. I would still like to suggest taking an additional look at some other rollers I have listed for you on the upper right side of this page. Compare yours with the thickness of the roller housing, the height, and the diameter of the wheel. That should determine which roller is the best match for you.
