SUPRAX SUP Storage System – Dual Board Add-On Kit

Overview

Expand your boat's paddleboard storage with the SUPRAX SUP Storage System Dual Board Add-On. Designed for boat owners who want organized, secure board storage without relying on improvised bungee arrangements, this add-on kit provides two additional racks for accommodating a second stand-up paddleboard.

Constructed from sandblasted, anodized 6061 aluminum alloy, the racks feature die-cut EVA protective foam and heavy-duty shock cords to help secure boards during storage. The rotating clamp design accommodates angled stanchions, while the mounting system is designed for compatible 7/8" and 1" rails.

Important: This is an add-on package for an existing SUPRAX Single Rack System (#50050), which is sold separately. It is not a complete standalone storage system.

Key Features & Benefits

• Dual-Board Storage Expansion: Adds two racks to a compatible existing SUPRAX single-rack setup for storage of an additional paddleboard.

• Marine-Oriented Aluminum Construction: Made from sandblasted, anodized 6061 aluminum alloy for a refined finish.

• Protective EVA Foam: Die-cut, heat-pressed EVA foam helps cushion board contact points during storage.

• Heavy-Duty Shock Cords: Help hold boards in place within the rack system.

• Compatible Rail Sizes: Designed for 7/8" and 1" rails, subject to the mounting configuration.

• Rotating Clamp Design: Allows mounting on angled stanchions for greater installation flexibility.

• Includes Add-On Mounting Hardware: Supplied hardware is intended to attach the additional racks to a compatible existing single-rack system.

• Boat or Wall Storage Applications: The SUPRAX storage system is described as suitable for securing boards to a boat or wall; confirm the specific mounting requirements for your installation.

Why This Product Stands Out

The SUPRAX Dual Board Add-On expands an existing board-storage setup while maintaining a coordinated marine appearance. Its anodized aluminum construction, protective EVA foam, and rotating clamp design provide a purpose-built alternative to improvised storage solutions for paddleboard owners who want to make better use of available space.
