Arnall’s Universal Dual Arch Cover Support System


Out of stock



Our strongest Support System is now available! The new Universal Dual Arch Mount doubles the strength of the Arch Support System! We know you will love it!

This system is ideal for Aluminum boats that have non-standard rails. This bracket adjusts from .5 to 4.75″ and can be used horizontally or vertically. This also works great if your metal sheeting goes all the way to the railing.

The purpose of this invention is to keep your pontoon boat dry by creating a boat cover customized with 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).

The standard post design that comes with most pontoon boats does not provide much support close to the rails and puts a tremendous strain on the fabric where it pokes into it, and also indents your carpet on the floor – sometimes the wind blows the cover and the poles fall over.

You must also provide your own PVC pipe and boat cover. Instructions are included. PVC is less than $2.00 per 10′ foot stick – available at all Home Depot, Lowe’s or just about any local hardware store. Boat covers should be new and polyester with a recommended weight of 300 denier.

Thinking about northern winter snow? No problem! The instructions show you how to winterize your supports with some additional PVC to take on the weight of winter snow and ice.

(However, we highly recommend not leaving ice, snow or rain accumulation on boat covers for any length of time. Doing so will result in damage to your boat and accessories and may void your cover warranty.)

Once you’ve set up this system, no tools are required to remove and re-install the brackets. Quick On, Quick Off!!

Feel free to contact us if you are unsure which system is best for your boat! We appreciate your questions!
