Stopends are used to cap off the gutter at the end of the run. These self-locking stopends can be used on both the right and left side of a fitting or length of gutter.Our steel gutter stop ends feature a rubber seal and are installed by pressing or tapping the stop end in place using a soft faced hammer. We recommend using a small bead of silicon around the inside of the gutter at the joint. The rear top tab should be bent around the back of the gutter.
