AIRHEAD Tube Keeper stern-mount tube securing system — 2" adjustable straps, 3-1/4" suction cups

AIRHEAD Tube Keeper is a stern-mounted strap-and-cup system that locks towable tubes to your boat so they won’t slide or fly off while underway.

Keep passengers safe and free up seating by fastening tubes to the back of your boat instead of holding them down. The Tube Keeper combines wide adjustable straps, elastic loop cords, and oversized suction cups so you can attach most towables quickly and remove them just as fast. It’s a simple retrofit that reduces onboard clutter and the risk of sudden tube loss during towing.

How does the Tube Keeper attach to my boat and tube?

Installation is tool-free and adaptable: wrap the two-inch adjustable straps around the tube’s built-in handles, then secure the other ends to the boat using either giant 3-1/4" suction cups or stretch cords that loop to a cleat or rail. The straps tighten to hold the tube snug against the transom.

• Straps wrap around tube handles for rapid attachment
• 3-1/4" suction cups adhere to smooth transoms or swim platforms
• Elastic loop cords fasten to cleats or rails when suction isn’t ideal
• 2" strap width distributes load and resists cutting into material

Will it fit different tube sizes and handle styles?

The adjustable 2-inch straps are designed to accommodate a wide range of handle layouts and towable diameters. Elastic loops and large suction cups provide alternative anchor points so you can secure single or tandem tubes, inflatable loungers, and many other towables.

• Adjustable buckles let you tighten for small or large tubes
• Works with most molded handles and rope-style grips
• Suitable for single or double tubes when used in pairs or multiples
• Elastic cords add flexibility where fixed anchors aren’t available

Can I rely on it for safety while towing and during rough conditions?

The Tube Keeper reduces the need for passengers to sit on tubes as a makeshift anchor, lowering the chance of falls or being thrown from the boat. While not a substitute for proper towing gear, it provides a secure secondary hold that helps prevent sudden loss of the towable when crossing wakes or maneuvering.

• Prevents tubes from sliding off the stern when accelerating
• Helps keep seating clear and passengers out of harm’s way
• Strap width and tensioning increase holding strength under load
• Use suction cups or cleat loops depending on water and transom conditions

How simple is storage and removal when I want the tube back in the water?

Removing the Tube Keeper takes seconds: loosen the adjustable straps, release suction cups, or unloop the elastic cords to free the tube for immediate use. When not fitted, the unit is compact and stows easily in a locker or under a seat.

• Quick-release buckles speed detachment before towing
• Suction cups peel off cleanly from smooth surfaces
• Compact straps and cords fold for locker storage
• No drilling or permanent fittings required

Who is this for? The AIRHEAD Tube Keeper is for boat owners and watersports enthusiasts who tow inflatables and want a safer, neater way to secure them when not in active use. It suits recreational boaters, rental operators, and anyone who wants to keep passengers off tubes while preserving seating space and reducing the risk of accidental detachment.
