The RotopaX 1.75 Gallon Extension is the stacking hardware you need to add a second container on top of the 1.75 Gallon RotopaX — giving you more capacity on a single mount point without adding additional mounting hardware or taking up extra space on your rack or carrier. Stack any size fuel or water pack on top of the 1.75 gallon base container and the two lock together into a secure, rattle-free unit on the same pack mount.
The extension is built from anodized aluminum, consistent with the same hardware quality used throughout the RotopaX mounting system. It threads into the pack mount base already holding the 1.75 gallon container and creates a new threaded connection point for the top container. The result is a clean, integrated stacking setup that holds securely even on rough terrain. Works with Standard, DLX, and LOX pack mounts.
As with all RotopaX extensions, the compatibility logic here is directional and worth reading carefully before ordering. This extension is specifically designed for stacking a second container on top of the 1.75 Gallon. If you are trying to stack the 1.75 Gallon on top of a 1, 2, or 4 gallon pack instead, you need the standard 1, 2 and 4 Gallon Extension — not this one. Getting the right extension for your specific stacking configuration matters.
