Thank you for reaching out to us. Take a look at our 10-324, 10-325, and 10-326 shower sweeps with drip rail. We also sell the 10-080 shower door magnet seal and end cap kit. Review the specifications for these parts and see how they compare with yours.
Normally, these shower sweeps with drip rail are attached to the bottom of the aluminum frame shower door using a screw like the 33-071. You will need to mark the hole in the door to the correct height needed and drill into the door frame to attach the screws. Just make sure you do not damage the glass or frame when drilling.
