When we list a box as a fit in our fit guide, the listing verifies that the vehicle and rack have passed our testing to allow you to safely carry the box. We do not check for, or list possible hatch interference due to the variability of different box and vehicle combinations.
This link, will walk you through determining if the box and vehicle combination you are looking at will cause interference with your hatch.
