If you need to attach something to a rigid, non-porous surface without drilling any holes, this is the best way to do it.

To make it easier for you to turn the SeaSucker into your solution, it’s made with two slotted holes in the top (for bolting whatever it is you’re mounting on there) plus a threaded (1/4-20) stainless insert. The 4″ size is rated to hold 120 pounds and the 6” SeaSucker vacuum cup is rated to pull up to 210 pounds – this is their biggest and strongest mount. It’s commonly used on bike racks and heavy-duty rod holders and dive racks. All metal parts are high grade stainless steel, even the springs inside our pump, for extra durability in the elements. Protective cap included.  Available in Black or White.
