Top stabilizer wheel

This white plastic wheel is clipped into the TOP frame of a patio glass sliding door. It appears to simply maintain the door in the upper track without a "wobble or lift" when you slide the door open and closed. My guess is this is about a 20 year old sliding glass door.

Is this by chance a Peachtree door? Check out our 84-082 Roller Guide. Look it over and see if you think this matches your old top guide.
