I would like help identifying the replacement wheels and the housing that holds them. I would like to be able to purchase the wheels individually if possible. These are from a Milgard window. I believe the Classic Series.
The housing that holds the wheels are 2-1/4" long.
The mounting screw holes in the housing are 1-7/8" center to center.
The housing is 7/16" wide and 9/16" tall.
The wheels are a 1/2" tall.
The overall width of the wheel is 3/8" wide and the part of the wheel that rides on the track is 1/4" wide.

Hi there. I'm afraid I'm uncertain if we have an exact match for these rollers. The dimensions of window rollers are incredibly specific. Start by looking at our 87-188 or 87-194. Double-check your dimensions in comparison and see if one of these might work for you. Let me know what you find.
