Hi
I've attached a few pictures. I need to know what shower door sweep to buy. The metal piece that is currently on the door in the second picture is 21 1/2 long and about 3/4 wide. I don't know what type of vinyl sweep was originally in the door. The shower door is 22 1/4 wide.

I took a picture of the metal piece that sits on top of the tile... that seemed important :-)
The house was built in 1968 - so the doors are pretty old.

Advice on what I need to buy would be greatly appreciated!

Hello and thanks for sending your images. I see you reference our 10-324 shower sweep with drip rail as a possible replacement for your current sweep. I also feel that this may make a good match. You just want to compare your measurements with ours to see if this is the right piece for you.
