I am looking for threaded suction cups 1 3/4":- 2 1/8": in diameter. The threaded stud must be molded into the rubber, or the suction cup must have a threaded female insert molded into the rubber in order to receive the threaded stud. The stud is to be 8/32-10/32 thread and should extend out of the cup aprox 3/8":. The stud should not be able to pass through the suction cup, so therefore should have a break in the threaded center, or something to stop it from passing through the other side .There should be no holes in the cup either except where the stud is inserted. Rubber composition should be a medical grade PVC, or possibly a Nitril, or something that is more flexible and conforming. Total height should be aprox 1 1/4": plus the stud suction cups threaded suction cups
