Compare ROAM Adventure Co. rigid mounts for 66L, 83L, and 128L rugged cases. Learn key differences in mounting style, hardware, and security to pick the right one for your rig.
Quick answer
Choose the 83L Rugged Mounts for quick-release convenience and lockable security. Pick the 66L or 128L Rigid Mounts for a permanent hard-mount solution when you don't need to remove the case often.
Mounting style matters more than size alone
The 66L and 128L Rigid Mounts use a hard-mount design that bolts directly to your roof rack or flat surface. They require tools to install and remove, making them best for semi-permanent setups. The 83L Rugged Mounts use a quick-release system that attaches in under 5 seconds and includes a lock for theft prevention.
All three mounts are designed for specific case sizes: the 66L Rigid Mount fits the 66L Rugged Case, the 83L Rugged Mount fits the 83L Rugged Case, and the 128L Rigid Mount fits the 128L Rugged Case. You cannot interchange them across sizes.
Hardware and installation differences
Both the 66L and 128L Rigid Mounts are made from .188 black powder-coated steel and have 1/4" holes for bolting down. They shoehorn into the tie-down channels of their respective cases. Neither includes mounting hardware, so you'll need to supply your own bolts and tools.
The 83L Rugged Mount uses a universal mounting base plate that works with virtually any roof rack. It comes with a locking mechanism but may require additional hardware depending on your rack's design. This mount is more expensive but offers faster installation and removal.
