Do I have the 55-178?

A distributor from Omaha says:
I am doing a replacement warranty on some older windows, possibly Survivor Series. Before I remove the window glass from the sash I want to have some glazing bead in case they break. The current ones are a little brittle.

The stock # 55-178 looks as it my work for the boxed one in the photo. The one with the interlock is the one I need to find. I would need 16ft of the boxed, 8ft of the interlock glazing bead.

Any help would be appreciated.

Thank you for your patience in this matter, Richard. We have just added the new 55-187 Glazing Bead, which I think you may be interested in. Take a look and let me know if you can use this as a replacement.
