Product Description
Hardy 1328992 HEUBSP02 Drag Knob (Black)
The Hardy 1328992 Drag Knob (Style No: HEUBSP02) is the primary external control for the disc drag system on the Hardy Ultralite DD (Disc Drag) series. As the main interface between the angler and the reel’s internal braking mechanism, this regulator knob allows for rapid, 360-degree adjustments to drag tension.
Machined from high-grade 6061 bar-stock aluminum and finished in a deep black anodization, this knob features a heavily textured, "slip-proof" grip. This ensures that even with wet hands or while wearing gloves, you can maintain precise control over a running fish. Its low-profile, ergonomic design is specifically engineered to prevent fly line snags during high-speed payouts.

Key Features
-
High-Traction Grip: Features aggressive knurling on the circumference, providing a secure feel in cold or wet conditions.
-
Linear Adjustment: Works in conjunction with the push pins to provide a predictable, graduated increase in drag pressure across the full rotation.
-
Impact Resistance: The solid aluminum construction is designed to withstand the accidental bumps and drops that often occur on the riverbank.
-
Signature Aesthetic: Maintains the high-end look of the Alnwick-designed Ultralite series, fitting perfectly with the "Reel Back" (1328991).
Maintenance & Lubrication
The drag knob is an external part that acts as the gateway to the sensitive internal drag stack. Keeping the threads and the underside of the knob clean is essential for a "premium" feel. We recommend using Deuthlon high-performance lubricants:
-
Thread & Seal Care: Apply a thin layer of Deuthlon Power Grease to the internal threads of the 1328992 knob. This prevents the aluminum threads from "galling" and creates a secondary waterproof barrier to keep grit away from the drag washers.
-
Smooth Indexing: Place a tiny dab of Deuthlon Power Grease on the detent path on the underside of the knob (where the Click Pin strikes). This will make the "clicks" feel smoother and higher-quality, reducing the "gritty" sensation of metal-on-metal movement.
