I am buying some 87-010 window rollers and I wanted to know if 2 9/16 roller wheels will fit in the plastic housing.

I just bought the 87-010 window rollers from your company. It comes with 1 roller wheel installed. You also sell just the 9/16 roller wheel and it looks like 2 roller wheels can fit in the window roller housing. I would like to know if they will so I can buy extra roller wheels.

There are 2 slots for rollers because it is adjustable. One slot is higher up than the other, to allow the wheel to sit higher or lower, as the case may be. They can only operate with just one wheel.
