Description The Tubus 3 part fixture straps are designed to secure your cargo on your Tubus rack – no need for ocky straps! The hooks are designed for Tubus racks, however will work with any tube diameters <14mm. The Straps are 60cms, with an additional 30cms of stretch so you can secure your sleeping bag or mat on to your rack easily. Note: Hooks not compatible with the Grand Expedition rack. For securing gear to your rack we also stock Voile Rack Straps which work perfectly with Tubus racks. And pretty much any other rack too.
