Shower door drip rail

Thanks for posting! Your shower door sweep can likely be replaced with one of our shower sweeps mad with a drip rail. We have one that looks similar in style and it comes in a few different lengths. 

Take a look at the 24" 10-324, 30" 10-325, and 36" 10-326. See if this style could work for your repairs.
