Two-Piece Split Shaft Spindle for 1-3/4″ Doors, 5/16″ Diameter
This two-piece split shaft spindle is designed for use with 1-3/4″ (45mm) thick doors. The spindle has a square profile and joins at the center, making it suitable for applications where the spindle must be inserted from both sides, such as doors that cannot accommodate a continuous shaft. Constructed for reliable operation, it is compatible with various door hardware brands including Marvin®, Jeldwen®, Cardaco®, and others.
Each spindle measures 4-3/8″ (111mm) in length with a 5/16″ (8mm) diameter. The two halves combine to create one complete square spindle, ensuring a precise fit. This component is intended as a direct replacement for square split spindles in entrance, passage, or other interior and exterior doors requiring this specification.
