Thanks for posting. Start by looking at our 81-289, 81-046, or 81-057. These rollers all have similar designs to yours, but compare the dimensions below and let me know if any of these options match what you have. If the dimensions differ, tell us in what way, and we'll see if we can find anything better for you.
We unfortunately don't have a version of this roller with only a 2" length. However if that's the only difference, then I wouldn't worry about it. That dimension is not really that important in my experience; there's functionally unlimited room in the bottom of the door for these to fit.
You can review a detailed pricing breakdown on that product's store page, linked to above. That's also where you can place your order. Please feel free to reach out if you had any other questions.
