SeaKnight NT40 Nylon Leader Line – Saltwater Shock Leader | 25LB to 200LB

The SeaKnight NT40 Nylon Leader Line is a heavy-duty shock leader built for serious saltwater fishing. NT40 super strong nylon delivers ultimate abrasion resistance and fast-sinking high density performance — essential for bottom fishing, rock and boat fishing where line abrasion, current and big fish are constant factors. Available in a wide strength range from 25LB light tackle up to 200LB big game.

Key Features

• NT40 super strong nylon — premium grade material for superior strength and abrasion resistance compared to standard nylon
• Ultimate abrasion resistance — withstands contact with structure, rocks, and rough-mouthed fish
• High density fast sinking — cuts through current quickly for better bait presentation and sensitivity at depth
• Wide strength range — 25LB through to 200LB for everything from light inshore to heavy offshore big game fishing
• Two spool lengths — 100M for lighter strengths (25–120LB), 50M for heavy strengths (150–200LB)
• Level line construction — consistent diameter throughout for reliable knot strength and presentation
