The Pontoon Boat Aluminum 4-Way Support Solution will never win a beauty contest, but it wasn’t designed to be pretty. It was designed for dependability with calibrated angles to complement and enhance the Arch-Maker in solving the dilemma that has plagued the pontoon industry since its inception… Keeping the pontoon boat canvas tight, secured, and easy to install and remove. Designed with our Northern friends in mind that need the extra support against the brutal Winter snow storms. The Pontoon Boat Aluminum 4-Way Support Solution replaces the traditional PVC 4-Ways included in the Pontoon Boat Canvas Solutions. They are made to last a lifetime and come with a limited lifetime replacement should they ever fail. The Pontoon Boat Aluminum 4-Way Support Solution is fabricated from solid 3/4" Marine-grade Aluminum rod and TIG-welded together for superior strength. LIMITED LIFETIME REPLACEMENT WARRANTY against manufacturer defects.
