Shower Door Seals for 3/8" Glass
3/8" (10 mm) is the most common glass thickness for frameless shower doors, and the one we install most. If your door is frameless and you are not sure, this is the most likely size, but measure to be certain.
Every seal below pressure fits onto 3/8" glass. Start with the most common ones at the top.

3/8" glass: common questions
Is my frameless shower door 3/8"?
Most are. A tape measure across the glass edge will read six 1/16" marks (about 10 mm). Heavier, high-end doors are often 1/2" instead.
What is the most common bottom sweep for 3/8" glass?
The CRL P990WS bottom wipe with drip rail. It is our go-to bottom seal on 3/8" frameless doors.
Which seal goes between a 3/8" door and a wall?
A multi-purpose 'H' wipe like the CRL P375HW on the door edge. We also use it on the hinge side where the door meets the panel that supports it.
Not sure where it leaks?
Match the leak to the seal in our guide, or let the Seal Finder do it.
