## Description

Introducing our newest support system featuring Dual Arches! Each bracket has two welded rods, giving you double the support with multiple access points for bungee tie down! Your purchase includes 5 sets of brackets, featuring laser cut and welded construction, and pure zinc-plated steel made in the USA. This is our strongest system designed to handle high amounts of wind, snow, wind and rain. The purpose of this invention is to keep your pontoon boat dry by creating a support system that arches the cover to shed off rain. The arch design is the best shape to keep rain out of the boat; our ancestors figured this out with the invention of the covered wagon. Because the cover is arched it will not rest on the seats, preventing “bleeding” into the boat fabric and will help protect the interior from getting bleached by the sun. Boat rails MUST be 1.25" square for this system to work. This system is ideal for newer boats where the seat cushions butt up to the railing. If you have rails that are not 1.25" square or if the metal sheeting goes up to the railing, then we recommend our Universal Brackets. You will need to provide your own PVC pipe and cut it to the dimension that works best for your boat model. We recommend gray electrical 3/4” schedule 40 PVC because it withstands heat better. PVC typically is less than $2.00 per 10' foot stick at most home improvement stores. Illustrated instructions are included, with directions for storing your boat for the winter. The Arch Support System is recommended for storage only, and is not intended to be left in the boat while in use. Please contact us if you are unsure if this is the best product for your boat. We have many style options based on the type of boat you own and the region that you live in. *Use only a new Polyester 300-600 Denier cover with this system* *NOTE Rods are TIG welded both sides - will never break under any load.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product!
*by D***. on June 17, 2017*

I had previously used a support system of center poles for my boat. With the center poles, wind would cause the tarps weight to shift and ultimately the poles to fall and the tarp to hold water. This allowed my tarp to tear. With the dual arch support system, I have had absolutely no issues. An F-1 tornado just went through my neighborhood and my tarp is still in place and holding no water. This system is a little pricey, but if you want to avoid replacing a very expensive tarp, it is the only way to go.

### ⭐⭐⭐⭐ Easy to install and very strong
*by T***F on October 1, 2017*

Easy to install and very strong. The key will be how it handle the snow and wind in a northeast winter. If it does well I will give it a five star rating.

### ⭐⭐⭐ Not a complete kit, you need to add the cross members!
*by K***R on November 11, 2019*

The paperwork should make clear that you have to cut and supply the pvc cross members which added another $50 or so to the installation.
