SIG Polypropylene Hinge
A special one-piece design molded from tough polypropylene. Easy to install. Can't clog up with glue like pinned hinges sometimes do. Due to the unique properties of polypropylene, this hinge can be repeatedly flexed back and forth against itself without ever splitting or breaking. These hinges will never wear out!

For standard size models with .049 -.60 size engines.
Very economical.
