A method of assembling a medical article, comprising:
- (a) providing a backing layer comprising:
- a conformable backing having a first major surface and a second major surface, and an opening through the backing layer to form a window;
- a first adhesive coated on at least a portion of the first major surface of the backing layer;
- a carrier releasably attached to at least a portion of the second major surface of the backing layer;
- a second adhesive coated on at least a portion of the second major surface of the backing layer proximate a perimeter of the window;
- and
- a liner releasably adhered to the second adhesive;
- (b) providing a self-supporting substrate comprising a first planar surface, and at least one side wall formed at an angle between zero to one hundred eighty degrees to the first planar surface, and a second planar surface connected to the at least one side wall in a form of flange;
- and
