The 6″ SeaSucker vacuum cup is rated to pull up to 210 pounds. Our custom housing has two slotted holes for back-plating accessories or mounting hardware and one center stainless steel insert for mounting anything with a standard ¼-20 machine screw. All metal parts are high-grade stainless steel (even the springs inside our pump) for extra durability in the saltwater environment.
The 6″ SeaSucker comes with a cap to protect the vacuum cup when not in use
