What are the roller dimensions of 23-288

The 23-288 dimensions are listed in the pictures on its shop page. For your convenience I have listed these dimensions below. Note that length actually isn't that important when it comes to sliding glass door rollers, as there's plenty of room in the door for variation there; it is critical that the height and width are a match though. Ideally the wheel diameter should be a match too, though adjustment of the roller allows for some play here (within 1/2").
