20x16x9. StarGrip Fixer Platform keepnets are made from thick carpsack cloth material and have a unique design for attaching to seat box systems. The fixed thread is fitted at a special fivedegree angle that allows gravity to take its course, setting your net to the perfect level. They are automatically setup wider apart to leave you room to fish. Also available with StarGrip fittings (Ref 50000) to enable you to tilt the net in multiple directions to your exact preference, as well as in a deeper carp model.
