Complete Guide to RUX System Components and Accessories

If you own a RUX system, you already know how versatile and durable these modular carriers are. But the real power of RUX lies in its ecosystem of components and accessories that let you customize your setup for any adventure. Whether you're organizing gear for a weekend trip or building a permanent kit for work, choosing the right add-ons can make all the difference.

In this guide, we'll walk through the essential RUX system components and accessories available, explain what each one does, and help you decide which upgrades are worth adding to your collection. From packing cubes to utility rails, straps to lids, you'll learn how to get the most out of your RUX system.

Packing Cubes: Organize Every Load

Packing cubes are the foundation of any organized RUX system. They allow you to separate gear, compress clothing, and keep small items from getting lost inside your main bag. RUX offers two sizes: the standard 10L and the larger 10L Ultra. Both are designed to fit perfectly inside RUX bags, but the Ultra version features a more durable fabric and reinforced seams for heavy-duty use.

If you frequently carry a mix of clothing, electronics, and tools, consider using multiple cubes to compartmentalize your load. The standard Packing Cube 10L is ideal for everyday carry, while the Packing Cube 10L Ultra is better suited for rugged environments where extra durability is needed.

• Use different colored cubes to quickly identify contents without opening.

Utility Rails and Corner Stays: Build a Rigid Structure

For users who need to mount accessories or create a stiff frame inside their RUX bag, the Utility Rail 300mm and Corner Stay 300mm are indispensable. The Utility Rail 300mm attaches to the interior MOLLE webbing and provides a stable platform for attaching pouches, lights, or other gear using the included hardware. The Corner Stay 300mm reinforces the corners of your bag, preventing sagging and maintaining shape even when fully loaded.

These components are especially useful for photographers, mechanics, or anyone who needs to carry heavy or awkwardly shaped items. By combining rails and stays, you can create a semi-rigid internal structure that keeps your load stable and accessible.

• Pair the Utility Rail with the Corner Stay for maximum structural support.

Straps and Lids: Secure and Protect Your Gear

No modular system is complete without reliable straps and sealing options. The Utility Straps (4-Pack) are versatile tie-downs that can be used to secure loads externally or compress contents inside. For lighter duty, the Tie-Down Straps Standard 56cm offer a quick and easy way to fasten gear. If you need to keep moisture out, the Press Seal Lid creates a watertight seal when attached to compatible RUX containers.

For carrying comfort, the Shoulder Strap (for Waterproof Bag, Pocket, Bag, Cooler Cube) is a padded, adjustable strap that works with multiple RUX products. The Compression Straps (Pair) are perfect for reducing bulk in packed cubes or bags, making your load more compact and easier to transport.

• Use the Press Seal Lid for electronics or sensitive items that must stay dry.

Specialty Accessories: Waterproof Tote and More

Beyond the core components, RUX offers accessories that expand the system's capabilities. The Waterproof Tote Bag 15L is a fully submersible bag that can be used as a standalone carrier or integrated into a larger RUX setup. It's ideal for kayaking, boating, or any wet environment. Combined with the Shoulder Strap, it becomes a comfortable sling for daily use.

Whether you're adding a tote for wet gear or a strap for easier carrying, these accessories ensure your RUX system adapts to your needs rather than the other way around.

• The Waterproof Tote Bag pairs well with the Shoulder Strap for hands-free carry.

Building the perfect RUX system is all about choosing the right components for your specific needs. Start with the basics like packing cubes and straps, then expand with rails, stays, and specialty items as your adventures demand.
