Hook and Base Set (91-266 504-91C) | Drop-In Spool Type | For Pfaff 1425 & 1445
Restore the mechanical integrity of your industrial machine with the Pfaff Hook and Base Set (Part #91-266 504-91C). This specialized 2-piece assembly is the "C" version of the drop-in spool system, specifically calibrated for the Pfaff 1425 and 1445 series. It provides the exact tolerances required for heavy-duty triple-feed applications.

The "C" Series Precision Advantage
The 91-266 504-91C represents the highest tier of factory-standard hook assemblies. Designed for machines utilizing the large-capacity drop-in spool system, this hook is built to handle the increased rotational mass and thread tension typical of automotive upholstery and heavy leather manufacturing. Choosing a Pfaff part ensures that the hook point timing and the "basket" clearance remain stable under high-torque conditions.

Key Performance Features
OEM Factory Certification: An original component manufactured to the precise metallurgy and geometry standards required for German-engineered machinery.

Optimized for Large Spools: Specifically designed for the high-capacity bobbin system, reducing the frequency of bobbin changes during long production runs.

Hardened Steel Hook Point: The hook point is precision-honed and hardened to maintain its edge, ensuring reliable thread loop pickup even when using thick, bonded threads.

High-Polish Finish: The internal race and base are micro-polished to eliminate friction, preventing "tension spikes" and thread shredding at high speeds.
