Evolve Tackle Straight Line Aligners are a fish-safe way to improve rig mechanics without shrink tubing or steaming. Moulded in a durable hard rubber compound with ultra-thin walls, they give the stiffness and low-profile performance of shrink tube while being reusable. Designed for straight shank hooks, they extend the angle of the hook eye to promote a more aggressive in-turn, helping the hook turn and secure a solid hold, particularly when targeting wary or pressured carp. Each aligner has overlength ends, so you can trim it down to the ideal length for your rig setup and preferred hooking mechanics. The translucent dark camo finish blends into the lakebed for a subtle presentation. - Sold in packs of 10 - Moulded hard rubber compound with ultra-thin walls - Reusable - Designed for straight shank hooks - Extends the angle of the hook eye for a more aggressive in-turn - Overlength ends can be trimmed to suit your rig - Translucent dark camo colour - No shrink tubing or steaming required
