There are several different types of sliding door edge seals available, including adhesive-backed seals, snap-in seals, and compression seals. Adhesive-backed seals are the easiest to install, as they simply adhere to the edge of the door with a strong adhesive. Snap-in seals are slightly more secure, as they snap into place along the edge of the door. Compression seals require a bit more effort to install, as they need to be compressed into the door frame to create a tight seal.
