Searching for operable transom seal

Hello,

We'd be happy to look into this for you but we would need to see an end profile photo of your seal uninstalled to compare to our inventory. Written-out dimensions are also important. Based on your description, it sounds like you may be looking for wool pile weatherstripping. If so, that is not something that we would generally recommend for a shower door that is consistently exposed to moisture but you are welcome to look through our selection here. Thank you!
