Wallace Mariner Seine Twine 1/4lb #21 White

The Wallace Mariner Seine Twine 1/4lb #21 in white is a commercial-grade nylon seine twine built for serious net fishing and fish trap work. If you're rigging nets or setting seines, you need twine that won't fray, holds knots reliably, and stands up to constant handling in saltwater or freshwater environments. This #21 twisted nylon delivers the strength and durability commercial fishermen and dedicated net builders have relied on for years.

Mariner twine is made from 100% nylon fiber, which means it resists abrasion, oil, and the chemicals you'll encounter on the water or in storage. The even diameter and consistent twist ensure uniform strength along the entire length, so you're not guessing whether a weak spot will let you down mid-set. Each 1/4lb spool carries approximately 915 feet of usable twine, giving you plenty of material for most seine rigging jobs without excess waste.

This is the kind of working twine that shows up on commercial fishing vessels and in the tackle boxes of experienced net fishermen who can't afford failures. It's not the flashiest option on the shelf, but it's the one that gets the job done consistently, year after year. Whether you're repairing a net, building one from scratch, or setting a fish trap, Wallace Mariner seine twine is engineered for the real work of fishing.
