replacement shower door sweep

I have a framed shower door that has a plastic sweep that needs to be replaced. I'm having trouble finding the correct part. It appears to just slip on the glass (1/4 inch thick) and has a drip rail on the inside to direct water away from the base of the door. The sweeps I have seen appear to be for frameless doors and have a section on the bottom which would not be suitable for my door as it would hit the frame. I'm hoping you can advise what sweep is required for my door (it's 28.5 inches in length and the glass is 1/4 inch thick) thanks for any assistance you can provide.

Thanks Paul. I originally didn't think this was the correct sweep as mine does not have the double plastic strip on the bottom and I thought the door would not close because of them. After your response I rechecked mine and realized that mine may have originally had those but they have broken off....and of course, that is probably why it is leaking!! Thanks for your help.
