FAQ

Which extension should I choose?
The extension is selected by the size of the base container, not the upper container.

Is this a complete mounting system?
No. It works with a primary pack mount and compatible containers.

Does an extension preserve LOX security?
No. Using an extension bypasses the locking function of a LOX mount.
