Our Kwikflip, The Hidden Hinge Elbow, is a one-piece specialty elbow that creates its own hinge. This completely assembled and ready to install elongated elbow allows raised downspout to stay in place without special clips or Velcro. Simply slip the elbow on the home’s existing downspout and screw in place same as a regular elbow and attach the appropriate length of downspout needed to disperse the water to the Kwikflip. The Kwikflip, manufactured from .019 gauge aluminum, comes in both 2×3 and 3×4 sizes for both the A and B-style applications. All elbows come individually wrapped in polybags to help protect the elbows
