Hollister Adapt - Barrier Extenders are curved adhesive strips that are placed over the border of your ostomy flange to create a larger adhesive area. They act as a frame around the skin barrier to keep the edge of the flange from lifting off the skin and also provide an extra layer of protection if a leak occurs. The hydrocolloid adhesive formula is stronger and more gentle on the skin than other types of tape. These flange extenders flex and move with your body for maximum comfort. Latex free. Box of 30 strips.
