Each bracket has two welded rods, giving you double the support with multiple access points for bungee tie down! Your purchase includes 4 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. For boats 24' or greater we recommend 5 sets. 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. ## Features - To see other styles of Arch Support Brackets, search "Pontoon Arch" - Railing must be 1.25" square - Includes 4 Sets of Dual Cover Arch Support Brackets - Best Snow Load when combined with uprights per instructions. - Comes With Instructions-Plus Steps To Winterize and Strengthen ## Technical Specifications | Specification | Value | |---------------|-------| | Brand Name | Extreme Marine Products | | Manufacturer | Extreme Marine Products | | Part Number | 37916 | ## Images ![Arnall's Dual Arch Support System for Pontoon Covers- 4 Sets - Image 1](https://m.media-amazon.com/images/I/81KgCFTSx4L.jpg) ![Arnall's Dual Arch Support System for Pontoon Covers- 4 Sets - Image 2](https://m.media-amazon.com/images/I/81qJ-RDZvWL.jpg) ![Arnall's Dual Arch Support System for Pontoon Covers- 4 Sets - Image 3](https://m.media-amazon.com/images/I/91516yoK1QL.jpg) ![Arnall's Dual Arch Support System for Pontoon Covers- 4 Sets - Image 4](https://m.media-amazon.com/images/I/91AfvGrb1uL.jpg) ![Arnall's Dual Arch Support System for Pontoon Covers- 4 Sets - Image 5](https://m.media-amazon.com/images/I/91hK6hiEF6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great but avoid 2” PVC *by C***N on August 13, 2023* Used 2 seasons now. The hardware is thick and durable. Will outlast the boat. Only issue I had was thinking i could bend 2” pvc per the instructions. Use the 2 smaller pvc per bracket and you’ll be good. ### ⭐⭐⭐⭐ System worls well *by J***S on March 3, 2013* System works fine. I added some tape to pad the conduit's sharp impressions made on the boat cover and extend its ware. Conduit is not part of the system and is purchased locally at the builder supply. ### ⭐⭐⭐⭐⭐ I would recommend these to build a sturdy support to protect your ... *by P***L on October 12, 2015* At $180 for 4 sets of dual arch supports, these are expensive but are worth the money.They are made well and will hold up to snow, bigger pvc pipe, etc.My pontoon, Aqua Patio 240 SL, has seating cushions 6" above the top rail along with panels up to the top rail in areas.My concern when ordering was, that the bracket rise would not be enough to clear the cushions. -Not an issue. @ 6" and pvc pipesshould not put impressions in the seating cushions.My other concern was not being able to bolt the brkts properly due to panels going up to the top rail in areas.The design of these brkts to either bolt on, or hold on with bungee cords solves this issue.I would recommend these to build a sturdy support to protect your boat during the Winter. ## Frequently Bought Together - Arnall's Dual Arch Support System for Pontoon Covers- 4 Sets - Star Brite 087616 Ultimate Aluminum Polish W/Ptef - RVMasking 1200D Partial Reinforced Waterproof Marine Grade Pontoon Boat Cover with Motor Cover for Length: 17'-20', Beam Width up to 102", Gray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/36305098-arnalls-dual-arch-support-system-for-pontoon-covers-4-sets](https://www.desertcart.co.za/products/36305098-arnalls-dual-arch-support-system-for-pontoon-covers-4-sets) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
