Choose the RotopaX Pack Mount that fits your adventure. These mounting kits let you securely attach RotopaX and FuelpaX containers to the SeaSucker RotopaX Tank Mount . Choose from three options based on your needs: simple and affordable, maximum grip, or added security. Standard Pack Mount Simple, secure, and budget-friendly. The Standard Pack Mount provides a reliable way to mount RotopaX containers to your SeaSucker RotopaX Tank Mount. Place your container on the mount and twist until tight. DLX Pack Mount RotopaX's most popular Pack Mount. The DLX provides superior mounting for RotopaX and FuelpaX containers, with a unique handle design that gives you extra leverage to tighten your container securely against the mounting surface. Simply align the mount with the container's dimples and twist until tight. LOX Pack Mount Maximum security for your RotopaX containers. The LOX Pack Mount features the same high-grip handle design as the DLX, plus a locking cylinder to help protect your containers from theft while you're off exploring. Align the mount with the container's dimples, twist until tight, and insert the lock cylinder for added security. Note: Using the LOX Pack Mount with an extension will defeat the locking capability.
