Made from soft rubberised material to grip most popular sized top kits (5mm-7mm) without causing damage. The perforated design serves several purposes, the main advantage is to counteract the vacuum effect which can prevent bait from releasing in a conventional pot, it also reduces the weight on the end of your pole and reduces wind resistance. Supplied with four lids in two different colours, the orange version is easily visible to make sure the pot is fully turned before you empty it.
