Hello, Chris! Your windows definitely need glazing bead, yes. These are what hold the glass in the sash frame. If there's no glazing, then your glass will fall out of its own volition. Yours in particular looks like our 55-029, but look over our pictures and dimensions for this product to confirm. The video below should be of help to you, too. This shows you how typical glazing bead can be replaced. |
