Window sash plastic moulding
Looks like a kind of glazing bead. Can you show me a picture of the end profile? That will let us see the shape, which is an essential part of identification. Knowing the size of the shape would also be a huge help.
Please make sure the end profile you show us is whole and undamaged. I know that it's probably brittle and prone to cracking, but please try your best. If the sample is too damaged then we won't be able to match it up to anything.
Thanks for getting back to us. I believe you have a Rollyson window that uses the 55-158-6 white snap-in glazing. Please compare this to your sample to confirm.
Hello! We had suggested the 55-158-6 to that customer. Have you looked at this glazing yet? Assuming that yours is the same as their photo, then it should be worth considering.
