When you need roof space but don’t have factory rails, these vacuum cups give you a quick, secure way to mount gear. The SeaSucker Monkey Bars use four vacuum mounts that attach to metal, glass, or fiberglass in seconds—no drilling or special fit kit needed. Each cup holds up to 120 lbs of pull strength, and the orange indicators show when the seal is secure. You can move the mounts to any position on the bars for just the right spread to fit your gear.
Whether it’s kayaks, bikes, or a cargo box, the 60" long by 1-1/4" diameter round bars give you plenty of room and work with most clamp-on accessories. The aluminum construction keeps weight down to just 12 lbs for the full rack but still supports up to 150 lbs (always follow your vehicle’s roof load rating). The black powder-coat finish resists corrosion and looks clean on any setup.
When you’re not hauling gear, the Monkey Bars break down in minutes. The two crossbars screw apart so you can store them in your trunk, garage, or even a suitcase. For smaller loads, remove the center section and use them as 48" bars instead of 60". It’s a simple design built for people who like gear that adapts to whatever trip comes next.
Because the cups attach directly to smooth surfaces, this rack works across different vehicles—perfect for switching between rides or using on rental cars. You can pop it on before a weekend trip and remove it just as fast when you’re done. Add an optional window cable anchor and cable lock (sold separately) if you want a quick theft deterrent while parked.
From kayaking weekends to hauling camping gear, these round bars are ready for almost anything. The standard diameter fits popular carriers from major brands, so there’s no need to buy new mounts. Once the cups are pumped down and secure, you’ve got a strong, versatile platform for all kinds of outdoor adventures.

still working as when new. I do put the white cup covers on after every use. I thnk that is important to keep the cup in good shape. The only suggestion I have is that the rail should be a aerodynamic blade style. Otherwise great product.

The manufacturer will reach out to you. When installing the bars you will want to make sure that the surface is clean and then press the pumps several times until the orange bands disappear. Make sure to check the plungers before you get into the vehicle. if you see the orange indicator bands show simply re-pump the plungers.

One year later.... Finished a complete lap of America. Drove 14,000 miles with this rack. Suction cups held a large Thule cargo box quite well. I still checked the cups every few days, but a couple of quick pumps and all was good. We even camped in Yellowstone with 15 degree temps at night. The entire rack worked well.
