FAQ

A spindle is the metal rod that doorknobs and levers are mounted on.

Regular spindles (as opposed to dummy spindles) extend through the door and latch to the doorknob on the other side. Once backplates and doorknobs are installed, spindles are completely hidden.

Antique door hardware was made with many spindle varieties: threaded, plain, and split, to name a few. Our 9/32" square steel spindles are all threaded 20tpi (threads per inch) - the most common size, and the standard threading for most new doorknobs designed for threaded spindles.

Except for the Dummy Door Set, all Interior Door Sets come with spindles.
