Developed for wacky rigging and neko style worms, the G7 Worm Protect Tubes are a new concept that extends the life of your soft plastic worms and are quick and easy to apply. G7 Worm Protect Tubes are made from durable silicone that stays in place and doesn’t slide up and down the worm like traditional O-rings. They are also wider and have more surface area in contact with the worm, which prevents your soft plastic worms from tearing as easily when fighting fish or going through cover. Made to work with the G7 Worm Tube Pliers, simply place one on the end of the pliers and stretch the tube open, then slide your soft plastic worm through the tube to the desired position and release. It’s that simple. Available in a wide range of sizes to accommodate almost any size worm, the G7 Worm Protect Tubes are a more effective and durable method for wacky rigging or neko rigging.
