shower door frame is 27 1/4" wide, 3/8" thick bottom edge, metal strip is 26 1/4". This is a over 20 year old shower door. Rubber and hardware rotted and deteriorated due to very hard water. Attaching screws rusted out.

Greetings from SWISCO.com. Since you have hard water in your area and seeing the deterioration of your shower door sweep, we suggest a new complete shower door sweep with a drip rail, our 10-325, and 33-071 stainless steel installation screws.
