I have a casement window in my bathroom with a handcrank that opens a plexiglass skylight - roof is at 45deg angle

THe plexiglass lies on an aluminium frame

The weatherstrip (about 35-40 years old) has deterioted and must be replaced.

Profile is square S-shape(two U's - open at opposite sides) - about 1" wide

I do not see any manufacturer's names

Can you guide please?

Regards

Richard

Thank you for reaching out to us, Richard. We're happy to look into this, but we'll need more information. Can you remove an undamaged sample of the weatherstrip and show us photos of the end profile?

Hi Emily
Pic 1 shows drawn image of weatherstrip profile
Pic 2 shows weatherstrip (compromised) - I do not have a full intact strip
Pic 3 shows profile view (which I "reconstructed")
This forms part of my plexiglass skylight
o Outer section is outer plexiglass
o inner aluminum frame
o inner plexiglass
thanks for your help
btw: This is 30+ years old ...

Thank you kindly, Richard. Unfortunately, we don't sell anything like what you show here. I'm afraid we aren't sure who might. Since the seal is old, you could try consulting a local mom and pop shop. I can't make any promises, but they're sometimes more familiar with parts used in the area. I'm very sorry that we can't be of help.
