Hi, I would sure appreciate some help in identifying these two weather strips. They came off of a sliding glass door, the doors are not marked but I think they might be Anderson's. I hope your company may sell these so I can purchase them from you. I am looking for a beige color.

Hey, Mark. This closely resembles our 58-175 Pella leaf seal. However, this is specifically made for Pella setups. That doesn't necessarily mean it can't work for you, but it's something to keep in mind. Look over our measurements and see how well it matches up.
