This is a universally used gray flat style shower door sweep that is 36 inch long and 1-1/2 inch wide and can be cut to size. It is held onto the swinging shower door by a drip rail that is located on the bottom of the door. Easy Installation, just remove the screws from the metal strip holding the old sweep and remove. Cut the new sweep to size, determine how far down the sweep needs to hang and install by replacing the drip rail over it and re-installing the screws.
