Swivels are one of the most common pieces of fishing equipment. They are used to prevent fishing line from becoming twisted, which is one of the primary causes of stressed, freyed, weakened or tangled fishing line.

Swivels also are used to link two pieces of fishing line together, or to attach a leader to a fishing line. These Rosco Swivels are very durable, yet will pivot freely and are made with anti-corrosive material so as not to freeze up.
