Needing to replace shower door sweep ( I think that's what it's called ?) the original to the shower ( 2013 38 RE ) is brittle and needs replacing .... looked online and rv stores and though they make different door sweeps none thus far is matching what we need ??
It usually slides out of a groove (may has to loosen screws & use soapy water to lubricate it) & you should be able to find a replacement at most any home improvement store, at least mine wasn't rv specific.
