weatherstripping for a Alprod aluminum front storm door

Due to the door being old, they do not sell the correct replacement in Lowes or Home Depot. A sales floor associate from Home Depot suggested I look you up on line and order. I saw a "small T door sweep" Patio Screen Door Spline, 25'
Product Code: 59-237

The original one the is torn and hanging has a very small and thin T that slides into a extremely small channel on the bottom of the outside aluminum storm door. Not sure if the one mention above is the correct replacement.

Looking forward to your response.
