Spindle love

I had to specially order a longer spindle due to an antique door knobs that I bought for my new house! My contractor told me I needed a 4 inch Spindle to work, As my doors were a little bit thicker than usual. They arrived quickly, And they worked like a charm! Enjoying my beautiful new door hardware!

  • An old-style threaded spindle rod for doorknobs. Made of solid steel, this spindle is sturdy & durable. This particular spindle has a size of 3/8" - 20 threads per inch (TPI), which is a standard & common size for many doorknobs. Excellent for your reproduction doorknobs, or just a replacement for your old chewed-up spindles. Available in several lengths.
