Need replacement hardware for Leigh Full-Vu metal Bi-fold doors

Good question. It's a little hazy when it comes to the bottom pins you should use for a Leigh bifold door; basically, it varies by the era. Between 1967-1979, the 21-048 Leigh bi-fold threaded bi-fold door pivot pin was used. A thinner pin, our 21-062 bi-fold pin, was used for Leigh bi-fold doors between 1961-1967. You'll have to remove the old pins and measure their diameter, as well as the diameter of the caps atop the pins, then compare to your old hardware to determine which you need.
