Two parallel guides hold the keel while you work. An adjustable alignment unit straddles the base, ensuring that all bulkheads are square to the false keel. A set of ten metal screws makes the unit fully adjustable in height as well as width. Easy-to-assemble kit includes base, laser cut wooden parts, all necessary hardware, plus illustrated instructions for assembly and use. Base 24" x 4 1/2" #MS105 Price.....$34.99
