The CupClam drink holder can be mounted in either horizontally or vertically-mounted StarPorts, to hold mugs, stubbies, wine glasses, even wine bottles.
If you can’t hold your drink, the RAILBLAZA CupClam will.
Note: Some fabrics might be compromised by silicon, for the best installation result, please use 3M™ Tape Primer 94 on the inflatable surface before application.
