The Fred "Boom Boom" Roumbanis Signature Series Vertical Mount + Tumbler isn’t just another cup holder—it’s built for serious anglers who don’t have time for distractions. Designed in collaboration with Professional Bass Angler Fred Roumbanis, this combo keeps your drink locked in while you focus on landing your next giant hog.

The folding design keeps it out of the way when not in use, and when it’s time to lock in your drink, just twist it in place.

Paired with the double-wall vacuum-insulated Tumbler, your drink stays at the perfect temperature—hot or cold—for hours. Whether you're cruising across the lake or fighting a trophy fish, your drink stays secure, spill-free, and ready when you need it.

Roots in Aviation.

Our patented locking cup holder began as an innovative solution for aviation safety, securing beverages in aircraft cockpits—because turbulence and coffee don’t mix.

Then the pilots started asking, 'Can I have one for my boat, too?' And just like that, TwistLock went from the runway to the waterways.
