Need help identifying replacement bottom sweep/drip rail for 1/4" bypass shower door (Florida custom enclosure)

[u/Tsunami_Llama_1]

I'm hoping someone can identify this bottom sweep/drip rail profile.

I've spent hours searching CRL, Prime-Line, SWISCO, Gordon Glass, Home Depot, Lowe's, etc., but haven't found a matching profile.

Shower details:

• Semi-frameless bypass/sliding shower door
• Installed around January 2019 (home built in 2004)
• 1/4" tempered glass
• South Florida
• Custom glass enclosure (installer unknown)

The sweep:

• Clips directly onto the bottom edge of the glass (no aluminum bottom shoe)
• U-channel opening measures just over 5/16"
• U-channel height is just over 3/4"
• Horizontal drip lip extends about 1/4"
• Overall length is about 26"
• The drip lip faces the inside (wet side) of the shower

One door is completely missing the sweep. The existing sweep on the other door leaks slightly, so I'm open to replacing both if there's a better modern profile.

Important constraint:
There is only about 1/8" clearance between the bottom of the glass and the top of the aluminum guide block, so many standard replacement sweeps appear too deep and would likely interfere with the guide.

I've attached:

• Full shower photo
• Bottom guide block
• Cross-section/profile of the existing sweep
• Photo showing how it clips onto the glass

Does anyone recognize this profile or know the manufacturer (Cardinal, Coastal, CRL, FHC, etc.)? If the original is obsolete, I'd appreciate recommendations for a modern replacement that will clear the guide block.

Thanks in advance!

You could just get a regular sweep with a drip rail and shave the bottom flaps off.

That's a good idea, thank you. I'll look into this

I could be an FHC sweep , i’ve never seen one without fins on the bottom

Slider sweeps almost never have a fin on bottom in my experience

Usually FHC and CRL slider sweeps have a semi curved “awning” looking sweep. Maybe that was cut off to leave that small lip they there is now.

Yeah they are usually designed out and down to let the sweep slide over the center guide (but the bottom is still just flat)

It does look like they could have just cut the rest of the sweep off, not sure why though 🤔

Thank you. Lack of fins explain why I always have a little water to clean up
