1/2" glass: common questions
How do I know my glass is 1/2"?
Lay a tape measure across a bare edge: 1/2" is eight 1/16" marks (about 12 mm). Six marks is 3/8", the more common size.
What is the most common bottom sweep for 1/2" glass?
The CRL P912WS bottom wipe with drip rail.
Do 1/2" doors use different seals than 3/8" doors?
The seal shapes are the same; only the channel that grips the glass is wider. Always order the version made for 1/2" glass.
Not sure where it leaks?
Match the leak to the seal in our guide, or let the Seal Finder do it.
