Hello, Windows are aluminum, about 20 years old. Glazing is an approximate V shape with a groove at the top of the V. The inside edge of the V has a slight outward bend at the bottom. The outward facing leg of the V is 5/8" and the inward facing leg is 9/16". No markings found. Color of strip is black, windows are bronze. Thanks, K. Alder

We offer something similar to the part you are showing us. Please take a look at our 55-029 snap-in glazing bead and see if this could work in place of your current piece.
