Perfect solution for attaching things to Sportfish and Center Console Boats without drilling holes in your boat. To make it easier for you to turn our SeaSucker into your solution, we make it 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 6” SeaSucker vacuum cup is rated to pull up to 210 pounds - this is our biggest and strongest mount. It’s the one we use one our 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.
