Hi,
I'm wondering if you have something to replace the weather stripping in the photos. The foot is 3/16" wide. It is about 3/16" tall overall. The bulb part is about 0.09" wide at the base. It widens out to about 1/8" at the top.
The weather stripping fits into a grove that surrounds the outside of the slider. The first photo shows the weather stripping installed along the left edge and the empty grove into which the weather stripping is installed along the bottom.
This comes from a wood frame window manufactured in the late 80s. I think it was made by Lindal. I'm not sure about that.
Thank you for this service. It's great.
