SeaSucker 4.5 Inch Vacuum Mount With Flat-top Stainless D-ring Black - VM1013B

All the awesomeness of the original 4.5" SeaSucker, but with a stainless steel D-ring for holding ropes, straps, etc. Our vacuum cups lend themselves to an almost infinite number of uses. If you need to attach something to a rigid, non-porous surface without drilling any holes, this is the best way to do it.
