This Weighted Twistlock™ hook employs the same hook as the 5132 Twistlock™, but also features a non-movable weight attached to the shank. Designed for both fresh and saltwater fishing. The hook's added weight helps to sink or swim the bait into the strike zone. With its Twistlock™ Centering-Pin-Spring (CPS Patened), baits can be permanently secured by inserting the pin in the center of a soft plastic, which can then be screwed on the Twistlock™ coil spring to rig perfectly everytime! Ideal for weedless style fishing without having to add a separate weight.
