The QP-427 is like the big brother of the QP-400 thanks to its
extrusion 50% stronger and its versatile UNITRACKTM system
on the top of both sides. This track makes it compatible with the Multinautic® accessories and you will no longer have to damage your deck boards to install your accessories. With the QP-427, you can move your cleats simply with a 3/4″ size wrench.
