Designed to create safe helicopter rigs on leadcore and fused leaders, the Helicopter sleeve is made from a slightly harder rubber to provide cushioning and protect the lead link when playing a fish. The top bead is made from a softer rubber and features a stepped inner bore to ensure it can pass smoothly off the leader creating rigs which are 100% fish friendly. Supplied in Weed, Gravel and Silt to match your leadcore or leader, these slim components allow you to make safe, neat helicopter rigs every time.
