SeaSucker's vacuum mount is the perfect temporary yet durable mounting solution. Simply remove the housing to bolt via the slotted holes, or screw directly into the 1/4-20 threaded stainless insert. 

 

The stainless steel D-ring holds ropes and straps etc and the 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. 

 

 Rated to pull up to 120 pounds.
