Window bottom sash double pane rubber seal

Hi,

I'm replacing a fogged up window insulated glass for the bottom sash. When I took out the glass to measure, there is a rubber U strip that goes around the insulated unit to pad it before sliding back into the aluminum frame. The inside is the width of the dual pane, 5/8" and the height of the lip around the glass is .5". It is one continuous piece of rubber that goes around the glass unit. Sorry I don't have a photo, I put it back in the frame while I wait for the new glass to come!

Thanks for your help identifying!

Bill
