Fiat acrylic steam/shower unit. Need bottom vinyl door sweep. Purchased from Guildcrest ind in Canada.

Hello there!

Thanks for reaching out to us. I recommend you start by taking a look at our 10-320 sweep with a round top. Carefully review the specifications and compare them with your old sweep to see if they match up. 

These photos appear to be the same as the ones in your initial post. They don't tell us anything new, I'm afraid. 

The only other sweep we carry with a rounded top is the 10-327. We also sell the 10-326, 10-324, and 10-325 drip rails which include a sweep. Look these parts over and see what you think.
