The QP-427 is the top stationary dock system combining sturdiness, lightness and versatility. Designed like the QP-400 but with bigger side extrusions that have Multinautic’s special Unitrack™ system, it allows you to install cleats and accessories where you want without piercing the decking. Its unique custom designed aluminum extrusions will bring more than enough strength while keeping it light for an easy and simple installation.
